Impact of the linkage-to-care intervention on time to linkage after the first home-based referral

REGRESSION
Univariable and multivariable Cox regression models were conducted to explore the effect of the linkage-to-care intervention on linkage-to-care. These models were censored for death, migration, and end of study follow-up and accounted for cluster intragroup correlation with robust variance. Re-referral was studied as a time-varying variable with four categories according to the dates of re-referral: 0: “No re-referral”; 1: “At least one re-referral, all through phone calls”; 2: “At least one re-referral, all through home visits”; 3: “A least one re-referral through phone calls and at least one through home visits”. The analyses were adjusted for sex, age, HIV care status at referral, educational level, occupational status, knowledge of another HIV-positive person in the family, wealth index, distance to the nearest TasP or DoH clinic, trial round at first home-based referral, and trial arm. Prior work within the trial showed these variables were significantly associated with linkage-to-care within three months of referral [
