CD4 and HIV infectious disease: In the final multivariable logistic regression models, being married (adjusted odd ratio [aOR]: 2.50; 95 % confidence interval [CI]: 1.07-5.87), longer duration of HIV infection (aOR: 10.7; 95 % CI: 3.66-31.3), and syphilis co-infection (aOR: 2.58; 95 % CI: 1.04-6.37) were associated with a higher likelihood of ART initiation among subgroup of CD4 count <350 cells/uL.
