Prevalence, factors and association with academic performance of anaemia in Kandahar schoolchildren: a cross-sectional analytical study.
Article in BMJ 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
objectivesThis study aimed to investigate the prevalence and associated factors of anaemia and its association with the academic performance of schoolchildren in Kandahar, Afghanistan.
designThis was a cross-sectional analytical study. SETTING AND
participantsThis was a school-based study conducted among 1866 schoolchildren aged 6-14 years in Kandahar city from September to December 2023. Haemoglobin concentration was measured using a portable HemoCue Hb 301 analyser, while the WHO age-adjusted cut-off for haemoglobin was used to classify anaemia. Data were analysed by using descriptive statistics, the χ² test and multivariate logistic regression.
resultsIn this study, the mean age of the children was 9.1 years, 61.1% (1138/1866) were boys, 83.6% (1560/1866) had illiterate mothers, and 81.3% (1517/1866) belonged to poor families. Prevalence of anaemia among schoolchildren was 64.1% (1196/1866), while 20.8% (388/1866), 41.7% (778/1866), and 1.6% (30/1866) were suffering from mild, moderate and severe anaemia, respectively. Main associated factors of anaemia were being male (adjusted OR (AOR) 1.4, 95% CI 1.1 to 1.7, p=0.003), unemployed father (AOR 1.5, 95% CI 1.1 to 2.2, p=0.020), poor family (AOR 2.3, 95% CI 1.8 to 2.9, p<0.001), large family (AOR 1.2, 95% CI 1.0 to 1.6, p=0.048), history of intestinal helminths (AOR 1.3, 95% CI 1.0 to 1.6, p=0.017) and decreased meat consumption (AOR 2.0, 95% CI 1.6 to 2.5, p<0.001). Children with anaemia had significantly lower academic performance.
conclusionsPrevalence of anaemia was very high and is a severe public health problem in schoolchildren of Kandahar. Based on the known consequences of anaemia on academic performance, the education and health authorities of Afghanistan should take serious steps to alleviate this problem. Periodic iron supplementation and deworming, as well as daily iron-rich mid-day meal programmes, should be started for both boys and girls in schools.
