  1. Estimates: Coefficients Correspond to the log Median Survival Time; Estimate for Age corresponds to a year increase in Age; Estimate for Weight corresponds to a Kilogram increase in Weight; CI: Confidence Interval; LCL: Lower Confidence Limit; UCL: Upper Confidence Limit; BFS: Bedridden Functional Status and its reference category is Working Functional Status; AFS: Ambulatory Functional Status and its reference category is Working Functional Status; CS (IV): Clinical Stage IV and its reference category is Clinical Stage I-III; CD4%16–28: Cluster of Differentiation Agent Four Percent 16–28 and its reference category is Cluster of Differentiation Agent Four Percent 12–15.
