Pooled multivariate hazard ratios among subgroups of studies estimating the effect of TB on all cause mortality in HIV positive individuals.

*The weights are from the random effect analyses if p<0.05 and the weights are from the fixed analyses if p≥0.05;
†The HR indicates the effect of TB on all cause/AIDS related mortality because López Gattell, et al (2008) 11 reports the effect of TB on AIDS-related mortality;
‡For both studies the multivariate hazard ratios as assessed by the marginal structural Cox proportional hazard have been included;
§Analyses number 2.1 formed the basis for the sensitivity analyses.
