The influence of vitamin A status on iron-deficiency anaemia in anaemic adolescent schoolgirls in Myanmar.
Trial report in Public health nutrition, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
objectiveThe present study was conducted to investigate reasons for the high prevalence of anaemia among adolescent schoolgirls and to elucidate the role of vitamin A in contributing to Fe-deficiency anaemia (IDA).
designAmong 1269 schoolgirls who were previously screened for anaemia (Hb < 120 g/l), 391 anaemic girls were further assessed for Fe, vitamin A and subclinical inflammation status. Fe and vitamin A indicators were corrected for inflammation and were compared in the Fe-deficient and non-deficient groups as well as between those with and without inflammation. Logistic regression was done to determine whether vitamin A status and subclinical inflammation were risk factors for Fe deficiency. The differences in Fe status among tertiles of vitamin A concentrations were assessed using ANOVA.
settingMyanmar. SUBJECTS: Adolescent schoolgirls (n 391).
resultsOne-third of the anaemia (30·4%) was IDA. Prevalence of low vitamin A status (serum retinol <1·05 μmol/l) was 31·5%. Fe and vitamin A status were significantly different between the IDA and non-IDA groups and also based on their inflammation status. Logistic regression showed that low vitamin A status was a significant predictor for being Fe deficient (OR = 1·81; 95% CI 1·03, 3·19 and OR = 2·31; 1·31, 4·07 in the middle (1·056-1·298 μmol/l) and low (≤1·056 μmol/l) vitamin A tertiles, respectively). ANOVA showed that better Fe status was associated with a higher concentration of serum retinol but only in IDA.
conclusionsFe deficiency was not the main cause of anaemia in the present population. The role of vitamin A as well as other micronutrients should be taken into account in addressing the problem of anaemia.
