Effect of the intervention on sustained a viral suppression for all study intervals through 6‐month postpartum visit for every participant with two or more VL test results in two separate study intervals, and varying threshold of VL cutoffs among the Opt4Mamas study participants (n=820), February 2019−December 2021
| Variable | Intervention (n=411) | Control (n=409) | Unadjusted RR b (95% CI) | p‐Value | Adjusted RR b (95% CI) | p‐Value |
|---|---|---|---|---|---|---|
| Viral suppression < 1000 copies/ml | 311/352 (88.4%) | 332/366 (90.7%) | 0.97 (0.92, 1.02) | 0.213 | 0.98 (0.93, 1.03) | 0.378 |
| Viral suppression < 400 copies/ml | 304/352 (86.4%) | 321/366 (87.7%) | 0.97 (0.91, 1.02) | 0.256 | 0.97 (0.91, 1.02) | 0.239 |
| Viral suppression < 40 copies/ml | 246/352 (70.0%) | 226/366 (61.7%) | 1.03 (0.92, 1.15) | 0.587 | 1.00 (0.89, 1.12) | 0.958 |
Abbreviations: POC, point‐of‐care; SOC, standard‐of‐care; VL, viral load.
a
Sustained viral suppression is defined as having viral load less than viral load cutoff in all viral load tests. For instance, for viral load cutoff <1000 copies/ml, a participant is sustained virally suppressed if the participant has viral load <1000 copies/ml in all viral load tests taken.
b
Risk ratio of intervention adjusted for number of tests.
