The effect of environment and in-utero HIV exposure on neurodevelopment in infants.
Article in AIDS (London, England), 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
objectiveEstimate the independent contributions of in utero HIV exposure and postnatal environment on neurodevelopment at 24 months of age.
methodsWe recruited mother-infant pairs from 2018 to 2022 during the second trimester of pregnancy in Malawi. Children who were HIV-exposed and uninfected (CHEU) and children unexposed to HIV and uninfected (CHUU) were followed to 24 months of age for neurodevelopmental outcomes. Environmental data was collected at 18 or 24 months.Neurodevelopment was measured using Malawi Developmental Assessment Tool, Communication Development Inventory, and Behavioural Rating Inventory of Executive Functions. Postnatal factors included maternal mental health, home learning environment, observed mother-child interactions, and socioeconomic status (SES). Exploratory factor analysis and structural equation modeling were used to simultaneously estimate the impact of exposures on latent developmental outcomes.
resultsThere were 643 children with 24-month outcome data, 49% of which were CHEU. Three latent factors were identified for neurodevelopment: Language, Executive Function, and Child Development. The factors did not correlate closely with each other and had different biological and environmental drivers. Quality of mother-child interactions was the strongest predictor of Child Development ( P < 0.001) and maternal mental health was a strong predictor of Executive Function ( P < 0.001). Despite adjustment for all environmental variables, CHEUs had lower Child Development scores than CHUU ( P = 0.01).Conclusion: Developmental scores of CHEU were lower than those of CHUU despite high maternal ART use, after accounting for postnatal environment. Despite this, the impact of high-quality maternal-child interactions on child development outweighed the impact of HIV exposure on neurodevelopment in this population.
