Childhood Linear Growth and Early Morbidity as Predictors of Adolescent Cognitive Ability in Malawi: A Prospective Observational Study.
Observational study in Acta paediatrica (Oslo, Norway : 1992), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
aimGrowth faltering and loss of development potential are common in low- and middle-income countries. We aimed to study whether linear growth before and after 2 years, height-for-age Z-score (HAZ) from 1 month until 13 years and morbidity during the first 3 years predict adolescent cognitive ability.
methodsCognitive assessment was done between 2018 and 2019 using Raven's coloured progressive matrices (N = 997), a measure of inductive reasoning and eye-tracking measures of saccadic speed (N = 760) and saccadic control (N = 618) among children whose mothers originally participated in a randomised clinical trial in rural Malawi. Linear regression was used to predict cognitive ability. The primary model was adjusted for age and sex, and the covariate-adjusted model for other prespecified variables.
resultsSaccadic control was predicted by a change in HAZ between 2 and 13 years in the adjusted model (coef -0.03, p = 0.04). Raven's score was predicted by change in HAZ between 1 month and 2 years (coef. 0.47, p < 0.05), and HAZ at 2, 5 and 13 years (coefs. 0.27-0.38, p < 0.05). Morbidity did not predict adolescent cognition.
conclusionLinear growth before 2 years of age and single HAZ measurements from 2 years onwards associated with later cognitive ability measured with Raven's test, but not consistently with eye-tracking assessment.
