CD4 and diabetes mellitus: Both PAFs that could be attributed to declined eGFR (7.39% in <30 year-old vs. 26.83% in 30–49 year-old vs. 52.19% in ≥50 year-old; pairwise comparisons, all P < 0·001) and diabetes (0.83% in <30 year-old vs. 4.00% in 30–49 year-old vs. 15.91% in ≥50 year-old; pairwise comparisons, all P < 0.01) increased across age groups, while PAF of low CD4 cell count was the highest in patients aged 30–49 years old (supplementary 6).
