Independent risk factors for very early (0–3 months after ART initiation) and early (3–12 months) mortality stratified by age.

Flow chart showing patients excluded from analysis.
<p>Of the 20 excluded patients, 17 were initiated on TDF-based first-line therapy, dual NRTI therapy or were already receiving a second-line regimen at time of genotype. The three protocol violations were: two patients on treatment for less than a year, and one with viral load <1000 copies/ml at the time of genotyping.</p

If there was no viral load ≤1,000 copies/ml then time was calculated from date of ART initiation.</p
