Anaemia and its association with iron, vitamin B
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
objectiveTo determine the frequency of anaemia and its association with iron, vitamin B
designCross-sectional study.
settingFamily health centres (primary care) in Antalya, Türkiye, 2019-2025.
participantsChildren aged 6-18 years with a complete blood count; the first eligible record per child was analysed (n=240 613).
main outcome measuresAnaemia, defined by WHO age-specific and sex-specific haemoglobin thresholds; iron (ferritin <15 µg/L or transferrin saturation <16%), vitamin B
resultsAnaemia prevalence was 9.5% (95% CI 9.4% to 9.6%), higher in girls (13.6%) than boys (4.2%) and rising with age (6-11 years 4.8%; 15-18 years 12.9%; both p<0.001). Most anaemia was microcytic (76.0%). Iron deficiency was present in 50.4%, vitamin B
conclusionsAnaemia remains common and largely preventable in school-age children and adolescents, with iron deficiency as the principal correlate. Adolescent girls are the priority group for iron-status screening and intervention.
