How To Calculate Intention To Treat Analysis

Introduction & Importance

Intention to treat analysis (ITT) is a method of analyzing clinical trial data where all participants are analyzed in the groups to which they were originally assigned, regardless of whether they received the intended treatment or not.

ITT is crucial as it maintains the benefits of randomization and preserves the integrity of the trial, providing an unbiased estimate of the treatment effect.
