Modeling the Potential Impact of Mentor Mother Programs on Vertical Transmission of HIV in Kenya.
Article in Open forum infectious diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Peer support provided by "mentor mothers" (MM) may increase retention in care for pregnant and breastfeeding women (PBFW) living with HIV, which can lead to improved viral suppression and prevention of vertical transmission (PVT). The impact of MM on PVT may differ among PBFW subpopulations with different baseline risks of antiretroviral therapy (ART) interruption. Method: We used a microsimulation model of HIV progression and care for PBFW living with recently acquired HIV in Kenya to evaluate an MM program that reduced the cumulative risk of ART interruption between initiation of antenatal care and 18 months of postpartum breastfeeding by 40%. We conducted this evaluation in 2 maternal populations: (1) newly positive (NP) pregnant women who initiate ART during antenatal care and are at greater risk of ART interruption and (2) known positive (KP) women who initiate ART prior to conception. We simulated live births, maternal deaths, and vertical transmission with and without MM services to determine the impact of MM. Results: In the absence of MM services, infants acquired HIV at a rate of 609 vs. 459 per 10,000 live births in the NP vs. KP populations. MM services reduced vertical transmission by 15.1% among NP women, compared to a 6.5% reduction among KP women. Conclusions: MM services can reduce vertical transmission among PBFW living with HIV, with greater potential for PVT among NP women compared to KP women. More research evaluating MM programs in these 2 maternal populations will help refine estimates of their PVT impact.
