results.df
component of the gComp
function
output is formatted as a data.frame. This makes it very easy to
immediately plot the results using ggplot2 or your
favorite R plotting functionality. Here’s an example for plotting the

The riskCommunicator
package facilitates the estimation
of common epidemiological effect measures that are relevant to public
health, but that are often not trivial to obtain from common regression
models, like logistic regression. In particular,
riskCommunicator
estimates risk and rate differences, in
addition to risk and rate ratios. The package estimates these effects
using g-computation with the appropriate parametric model depending on
the outcome (logistic regression for binary outcomes, Poisson regression
for rate or count outcomes, negative binomial regression for
overdispersed rate or count outcomes, and linear regression for
continuous outcomes). Therefore, the package can handle binary, rate,
count, and continuous outcomes and allows for dichotomous, categorical
(>2 categories), or continuous exposure variables. Additional
features include estimation of effects stratified by subgroup and
adjustment of standard errors for clustering. Confidence intervals are
constructed by bootstrap at the individual or cluster level, as
appropriate.
This package operationalizes g-computation, which has not been widely
adopted due to computational complexity, in an easy-to-use
implementation tool to increase the reporting of more interpretable
epidemiological results. To make the package accessible to a broad range
of health researchers, our goal was to design a function that was as
straightforward as the standard logistic regression functions in R
(e.g. glm
) and that would require little to no expertise in
causal inference methods or advanced coding.

data
|
(Required) A data.frame containing variables for |
outcome.type
|
(Required) Character argument to describe the outcome type. Acceptable
responses, and the corresponding error distribution and link function
used in the
|
formula
|
(Optional) Default NULL. An object of class "formula" (or one that can be coerced to that class) which provides the the complete model formula, similar to the formula for the glm function in R (e.g. ‘Y ~ X + Z1 + Z2 + Z3’). Can be supplied as a character or formula object. If no formula is provided, Y and X must be provided. |
Y
|
(Optional) Default NULL. Character argument which specifies the outcome
variable. Can optionally provide a formula instead of |
X
|
(Optional) Default NULL. Character argument which specifies the exposure
variable (or treatment group assignment), which can be binary,
categorical, or continuous. This variable can be supplied as a factor
variable (for binary or categorical exposures) or a continuous variable.
For binary/categorical exposures, |
Z
|
(Optional) Default NULL. List or single character vector which specifies
the names of covariates or other variables to adjust for in the
|
subgroup
|
(Optional) Default NULL. Character argument that indicates subgroups for stratified analysis. Effects will be reported for each category of the subgroup variable. Variable will be automatically converted to a factor if not already. |
offset
|
(Optional, only applicable for rate/count outcomes) Default NULL. Character argument which specifies the variable name to be used as the person-time denominator for rate outcomes to be included as an offset in the Poisson regression model. Numeric variable should be on the linear scale; function will take natural log before including in the model. |
rate.multiplier
|
(Optional, only applicable for rate/count outcomes). Default 1. Numeric variable signifying the person-time value to use in predictions; the offset variable will be set to this when predicting under the counterfactual conditions. This value should be set to the person-time denominator desired for the rate difference measure and must be inputted in the units of the original offset variable (e.g. if the offset variable is in days and the desired rate difference is the rate per 100 person-years, rate.multiplier should be inputted as 365.25*100). |
exposure.scalar
|
(Optional, only applicable for continuous exposure) Default 1. Numeric value to scale effects with a continuous exposure. This option facilitates reporting effects for an interpretable contrast (i.e. magnitude of difference) within the continuous exposure. For example, if the continuous exposure is age in years, a multiplier of 10 would result in estimates per 10-year increase in age rather than per a 1-year increase in age. |
R
|
(Optional) Default 200. The number of data resamples to be conducted to produce the bootstrap confidence interval of the estimate. |
clusterID
|
(Optional) Default NULL. Character argument which specifies the variable
name for the unique identifier for clusters. This option specifies that
clustering should be accounted for in the calculation of confidence
intervals. The |
parallel
|
(Optional) Default "no." The type of parallel operation to be used.
Available options (besides the default of no parallel processing)
include "multicore" (not available for Windows) or "snow." This argument
is passed directly to |
ncpus
|
(Optional, only used if parallel is set to "multicore" or "snow")
Default 1. Integer argument for the number of CPUs available for
parallel processing/ number of parallel operations to be used. This
argument is passed directly to |
We’ll demonstrate how to use the package with data from the Framingham Heart Study. The following information is from the official Framingham study documentation (https://biolincc.nhlbi.nih.gov/teaching/):
“The Framingham Heart Study is a long term prospective study of the etiology of cardiovascular disease among a population of free living subjects in the community of Framingham, Massachusetts. The Framingham Heart Study was a landmark study in epidemiology in that it was the first prospective study of cardiovascular disease and identified the concept of risk factors and their joint effects. The study began in 1948 and 5,209 subjects were initially enrolled in the study. Participants have been examined biennially since the inception of the study and all subjects are continuously followed through regular surveillance for cardiovascular outcomes. Clinic examination data has included cardiovascular disease risk factors and markers of disease such as blood pressure, blood chemistry, lung function, smoking history, health behaviors, ECG tracings, Echocardiography, and medication use. Through regular surveillance of area hospitals, participant contact, and death certificates, the Framingham Heart Study reviews and adjudicates events for the occurrence of Angina Pectoris, Myocardial Infarction, Heart Failure, and Cerebrovascular disease.
data(cvdd)
cvdd is a subset of the data collected as part of the Framingham study from 4,240 participants who conducted a baseline exam and were free of prevalent coronary heart disease when they entered the study. Participant clinic data was collected during three examination periods, approximately 6 years apart, from roughly 1956 to 1968. Each participant was followed for a total of 24 years for the outcome of the following events: Angina Pectoris, Myocardial Infarction, Atherothrombotic Infarction or Cerebral Hemorrhage (Stroke) or death.
NOTE: This is a “teaching” dataset. Specific methods were employed to ensure an anonymous dataset that protects patient confidentiality; therefore, this dataset is inappropriate for publication purposes.” The use of these data for the purposes of this package were approved on 11Mar2019 (request #7161) by NIH/NHLBI.
Research question: what is the effect of having diabetes at the beginning of the study on the 24-year risk of cardiovascular disease or death due to any cause?
Here, we will estimate the risk difference, risk ratio, odds ratio,
and number needed to treat, adjusting for patient’s age, sex, body mass
index (BMI), smoking status (current smoker or not), and prevalence of
hypertension (if they are hypertensive or not at baseline). Logistic
regression is used as the underlying parametric model for g-computation.
[NOTE: The CRAN version of this vignette has
reduced the number of bootstraps from 1000 to 200 to comply with CRAN
compile times. If you wish to perfectly recreate results from the
manuscript, change all of the instances of R = 200
to

The 95% CIs obtained from the riskCommunicator package represent population-standardized marginal effects obtained with g-computation. To ensure that the parameter estimates from each bootstrap iteration are normally distributed, we can also look at the histogram and Q-Q plots of bootstrapped estimates by calling:
plot(binary.res)
The histograms show the different effect estimates obtained by each
bootstrap resampling of the data and should be normally distributed if
the model is correctly specified. Q-Q plots help to verify that the
bootstrap values are normally distributed by comparing the actual
distribution of bootstrap values against a theoretical normal
distribution of values centered at mean = 0. If the estimates are
normally distributed, the plotted estimates (black circles) should
overlay the diagonal red dashed line.
First we obtain the odds ratio using logistic regression.

Note the use of confint.default
in the above call. The
typical call confint
does not return Wald-based CIs, so
we’ve forced it with confint.default.

Research question: what is the effect of having diabetes at the beginning of the study on the rate of cardiovascular disease or death due to any cause?
Here, we will estimate the rate difference and rate ratio, adjusting
for patient’s age, sex, body mass index (BMI), smoking status (current
smoker or not), and prevalence of hypertension (if they are hypertensive
or not at baseline). We have included timeout as the
offset
and a rate.multiplier
of
365.25*100
so that the estimates are returned with units of
100 person-years. Poisson regression is used as the underlying
parametric model for g-computation. (Note: for overdispersed count/rate
outcomes, the negative binomial distribution can be specified by setting
outcome.type
to “count_nb” or
“rate_nb”.)
