Maternal supplementation of vitamin B
Trial report 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
backgroundVitamin B
methodsThis double-blind, randomised controlled trial was conducted in two tertiary maternity care centres in India and Nepal. Pregnant women in their first trimester, following a vegetarian diet, were enrolled and randomised to receive either a daily oral supplement of 250 µg (group A) or 50 µg (group B) of methyl-cobalamin from enrolment to 6 months post partum. The primary outcomes were infant neurodevelopment assessed at 9-12 months using the Development Assessment Scale of Indian Infants and biochemical B
results531 mothers completed the study (group A n=255; group B n=276). There were no significant differences in baseline characteristics between mothers at both centres or in groups A and B. Mental developmental quotients (DQs) were higher in the infants of group A: 103.7 (7.7) than group B: 101.7 (8.8); p=0.008). This corresponds to a mean difference of 7.8 centiles (p=0.007). Mean motor DQs were not significantly different between the groups. Maternal vitamin B
