Optimization of the vertical transmission prevention program in Guinea: impact of the improvement plan on performance indicators at large-cohort sites.
Review in AIDS research and therapy, 2024. 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
introductionVertical transmission of HIV remains a major challenge in Guinea, especially, in low-resource rural areas. This paper presents the results of a pilot project designed to enhance the prevention of vertical transmission through a comprehensive improvement plan implemented across 66 large-cohort sites.
methodsData from 66 large-cohort of mother to child transmission prevention (PMTCT) sites from 2019 to 2022 were analysed to compare PMTCT metrics before (2019-2020) and after (2021-2022) the improvement initiative. Key indicators were reviewed, and trends were statistically analysed using Mann‒Whitney tests, with a p value less than 0.05 indicating statistical significance.
resultsThe implementation of this strategy significantly increased the antiretroviral therapy rate among HIV-positive pregnant women from 66 to 94%, and full antiretroviral prophylaxis coverage was achieved in infants. However, early infant diagnosis via polymerase chain reaction testing falls short of the national target, highlighting deficiencies in laboratory and specimen transport capacities. The study also revealed regional disparities in the use of PMTCT services.
conclusionThe improvement plan effectively enhanced antiretroviral therapy and prophylaxis use, demonstrating the benefits of structured interventions and capacity development. Despite improvements, challenges such as insufficient polymerase chain reaction (PCR) testing and uneven access to services remain. Future initiatives should aim to equip PMTCT sites with essential resources and promote community-driven health-seeking behaviours in underserved areas.
