PICOTsize: Sample Size Calculation for PICOT-Based Study Designs

Provides sample size calculators for the study designs covered by the PICOT framework, including cross-sectional, case-control, cohort, superiority, non-inferiority, and equivalence clinical trials, and diagnostic test accuracy studies, following Bhardwaj et al. (2024) <doi:10.4103/jfmpc.jfmpc_1675_23>. Calculations are performed using the 'epiR' package as a validated computational backend. Includes a 'shiny' application with a PICOT-based design wizard, an interactive sensitivity plot, and automatically generated Methods-section text for manuscripts.
