Prenatal and child malaria and child growth: evidence from a Ghanaian pregnancy cohort.
Article in BMJ paediatrics open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionAdditional investigation is needed to better understand the associations between prenatal and early child malaria and early childhood growth outcomes.
methodsWe leveraged the Ghana Randomized Air Pollution and Health Study which enrolled 1414 pregnant women from Kintampo, Ghana, and followed the mother-child dyads through the child's first year of life. We defined prenatal malaria exposure by histopathological examination of placenta tissue. We defined early child malaria exposure by active health surveillance over the child's first year of life and malaria rapid diagnostic testing when clinically indicated. We employed latent class growth analyses to construct growth trajectories for each anthropometric measure (weight and height and corresponding WHO z-scores, mid-upper arm circumference and head circumference (HC)), which we measured at birth, 3, 6, 9 and 12 months of age. We then used unadjusted and adjusted ordinal and multinomial regression to identify associations between prenatal and early child malaria growth trajectories, considered separately.
resultsOf the 1306 live births, 1144 children had prenatal and early child malaria exposure and growth data and were included in the analysis; 250 (21.9%) had prenatal malaria exposure, and 525 (45.9%) had early child malaria infection. Children with prenatal malaria as compared to those without had higher risk for poorer length growth (OR=1.46, 95% CI 1.08 to 1.98; multivariable OR=1.46, 95% CI 1.05 to 2.02), poorer length-for-age z-scores (OR=1.43, 95% CI 1.09 to 1.88; multivariable OR=1.53 95% CI 1.14 to 2.05) and smaller HC (OR=1.56, 95% CI 1.16 to 2.09; multivariable OR=1.43, 95% CI 1.04 to 1.98). Children with early childhood malaria as compared to those without had higher risk for poorer length-for-age z-score (OR=1.13, 95% CI 1.03 to 1.24; multivariable OR=1.12, 95% CI 1.01 to 1.24). Children with prenatal malaria as compared to without showed a trend for persistent stunting (multivariable OR=1.63, 95% CI 0.98 to 2.71).
conclusionMalaria beginning in pregnancy was associated with poorer growth outcomes. Public health preventative strategies beginning in pregnancy may reduce malaria incidence and improve early childhood growth.
