Study description

After identifying the populations of interest using CEM on age and calendar time, the distribution of baseline covariates will be evaluated in the 365 days prior to index. Continuous variables will be described using mean values with standard deviations and median values with interquartile range; categorical variables will be described as the number of patients and percent. For variables derived from diagnoses, procedures, and prescription codes, patients are assumed to have experienced the event of interest if the relevant code(s) are found among their claim records. Otherwise, it is assumed that the patient did not experience the event, thus resulting in no missing data for these variables
