Effect on infant illness of maternal supplementation with 400 000 IU vs 200 000 IU of vitamin A.
Trial report in Pediatrics, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled it.
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
BACKGROUND AND
objectivePostpartum vitamin A supplementation is a strategy used to combat vitamin A deficiency and seems to reduce maternal/infant morbidity and mortality. However, studies have shown that a dose of 200 000 IU (World Health Organization [WHO] protocol) does not seem to provide adequate retinol levels in maternal breast milk, infant serum, and infant tissue. The objective of this study was to compare the effect of postpartum maternal supplementation with 400 000 IU (International Vitamin A Consultative Group protocol) compared with 200 000 IU of vitamin A on infant morbidity.
methodsThis was a randomized controlled, triple-blinded clinical trial conducted at 2 public maternity hospitals in Recife in northeastern Brazil. There were 276 mother-child pairs that were allocated to 2 treatment groups: 400 000 IU or 200 000 IU of vitamin A. They were followed up for >6 months to evaluate infant morbidity.
resultsFever (rate ratio [RR]: 0.92 [95% confidence interval (CI): 0.75-1.14]), diarrhea (RR: 0.96 [95% CI: 0.72-1.28]), otitis (RR: 0.94 [95% CI: 0.48-1.85]), acute respiratory infection (RR: 1.03 [95% CI: 0.88-1.21]), the need for intravenous rehydration (RR: 2.08 [95% CI: 0.64-2.07]), and the use of antibiotic treatment (RR: 0.80 [95% CI: 0.43-1.47]) did not differ significantly between the 2 treatment groups.
conclusionsOur findings suggest that postpartum maternal supplementation with 400 000 IU of vitamin A does not provide any additional benefits in the reduction of illness in children aged <6 months; therefore, we do not support the proposal to increase the standard vitamin A dose in the existing WHO protocol.
