.add_utility Add utility values to a data frame
.check_uniqueness Check the uniqueness of groups This function takes a data frame 'df' and a vector of columns 'group_by', and checks whether the combinations of values in the columns specified by 'group_by' are unique. If the combinations are not unique, a warning message is printed.

figure_1_2_1 Figure 1.2.1: Paretian Classification of Health Change (PCHC) by Group This function computes PCHC categories between two time points for each subject, stratifies them by a grouping variable, and produces a single bar chart with side-by-side bars showing the distribution of PCHC categories.
figure_1_2_2 Figure 1.2.2: Percentage of Respondents Who Improved in Each EQ-5D Dimension, by Group This function calculates how many respondents improved in each dimension between two time points and summarizes the results for each group. The, it prodcuces a dimension-focused chart illustrating improvement percentages by dimension.
figure_1_2_3 Figure 1.2.3: Percentage of Respondents Who Worsened in Each EQ-5D Dimension, by Group
