Characteristics of attrition within the SuperMIX cohort of people who inject drugs: a multiple event discrete-time survival analysis.

ABSTRACT:

Background

Compared to the general population, people who inject drugs have poor health and wellbeing. Longitudinal studies can provide insight into factors driving these worse health outcomes but are subject to methodological challenges, such as cohort attrition.
