Note: ART = antiretroviral therapy, CI = confidence interval, HR = hazard ratio, MSM = men who have sex with men, NS = not selected.
↵* Model excludes patients whose cause of death was unknown and those who did not have 1 year of data to assess visit constancy.
↵† Variable not included in adjusted HR.
↵‡ Most recent within 6 months of first clinic visit.
