Incidence Rate of and Factors Associated with Loss to Follow-up in a Longitudinal Cohort of Antiretroviral-Treated HIV-Infected Persons: An AIDS Clinical Trials Group (ACTG) Longitudinal Linked Randomized Trials (ALLRT) Analysis

Abstract

Knowledge of differential LTFU can help researchers identify participants at risk of LTFU in longitudinal HIV cohorts and design retention strategies, thereby limiting study bias. The identified factors should be included in inverse probability of weighting models to account for LTFU.
