Participants with moderate CD4 counts (200–349 cells/mm3) had lower odds of infection compared to those with severely low CD4 counts (<200 cells/mm3) (OR = 0.712, p = 0.743), while those with normal/high CD4 counts (≥350 cells/mm3) also had reduced odds of infection (OR = 0.064, p = 0.130), though these results were not statistically significant. Here, CD4 is linked to infection.
