p-value* for heterogeneity 0.001    
*The differences were tested by standard analysis of variance method, where the square roots of TLC and CD4+ counts were used to normalize distributions. TAHOD=Treat Asia HIV Observational Database. TLC= Total Lymphocyte count. CD4+ count = CD4+ T-cell lymphocyte count cells/mm3. CD4%= CD4+ T-cell percentage. SD=Standard Deviation.
