All longitudinal GLMs accounted for within-patient correlation using a generalized estimating equation approach and controlled for demographics and time-dependent variables such as cumulative comorbidity history, resource utilization, and medication use.
The time to the first clinical event was evaluated using a Cox proportional hazards model, with goal achievement status as a time-dependent variable, controlling for patient demographics and other potential confounding factors such as cumulative comorbidity history, resource utilization, and medication use.
