Results of the Cox proportional hazards model of patient dropout.

*<p>Wald test.</p

Patient characteristics and comparison between dropouts and non-dropouts.

<p>Frequencies were compared via Pearson's chi-square test. Continuous factors were compared via the Kruskal-Wallis test. Median times from enrollment until CART start were estimated via the method of Kaplan and Meier and were compared by the log-rank test. IQR = Inter-quartile range.</p>*<p>Out of 6,900 total patients (5,178 non-dropouts and 1,722 dropouts) with WHO stage recorded within three months of enrollment.</p

Kaplan-Meier estimates of patient survival based on methods described in Table 3.

<p>Time is in months since start of CART.</p

Mortality estimates (%, 95% CI) at one year from enrollment and one year from ART initiation. Overall estimates based on entire cohort.

*<p>Combined estimates were produced as a weighted average of the individual (dropout versus non-dropout) estimates, taking into account the relative size of the two groups.</p
