Introduction Model‐based estimates of key HIV indicators depend on past epidemic trends
that are derived based on assumptions about HIV disease progression and mortality in the …

Introduction It is unknown whether HIV treatment guidelines, based on resource-rich country
cohorts, are applicable to African populations. Methods We estimated CD4 cell loss in ART …

Objective: We compiled the largest dataset of seroconverter cohorts to date from 25
countries across Africa, North America, Europe, and Southeast/East (SE/E) Asia to …

Background We investigated whether CD4: CD8 ratio and CD8 count were prognostic for all-
cause, AIDS, and non-AIDS mortality in virologically suppressed patients with high CD4 …

Background. CD4 count at start of combination antiretroviral therapy (ART) is strongly
associated with short-term survival, but its association with longer-term survival is less well …

Summary Background Measures of CD4 T-cell count and HIV-1 plasma viral load before
antiretroviral therapy are proxies for virulence. Whether these proxies are changing over …

Introduction Several methods have been proposed to estimate the time of HIV
seroconversion, including those based on CD4 cell depletion models. However, previous …

Background HIV cohort collaborations, which pool data from diverse patient cohorts, have
provided key insights into outcomes of antiretroviral therapy (ART). However, the extent of …

Objectives: To estimate prognosis by viral subtype in HIV-1-infected individuals from start of
antiretroviral therapy (ART) and after viral failure. Design: Collaborative analysis of data from …

Objectives Immune non-responders (INR) have poor CD4 recovery and are associated with
increased risk of serious events despite antiretroviral therapy (ART). A clinically relevant …
