The Effect of a Maternal Double Megadose of Vitamin A Supplement on Serum Levels of Retinol in Children Aged under Six Months.
Article in Journal of nutrition and metabolism, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT00742937 (Impact of Supplementation With Dual Megadose of Vitamin A in the Post-partum About Vitamin A Levels in Breast Milk, Serum Levels of Vitamin A and Iron in the Binomial Mother-son and Growth and Morbidity of Children Under 6 Months), which is not on this map.

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.

Abstract
Objective. To measure concentrations of serum retinol in children after the use of maternal vitamin A double megadose supplements. Design. Randomized controlled clinical trial. Setting. The study was conducted at two maternity hospitals in the city of Recife, in the northeast region of Brazil between August 2007 and June 2009. Subjects and Methods. 276 children/mothers were recruited after birth and the women received a 200,000 IU capsule of vitamin A. After ten days they were randomly assigned to two treatment groups. One group received a second 200.000 IU capsule, while the other received a placebo. The concentrations of retinol in the serum of the children from each group were measured at 2, 4, and 6 months. Results. 173 children completed the study. There was no difference between the two treatment groups (P = 0.514). The mean base retinol level was lower than that at four and six months (P < 0.001). Conclusions. The maternal double megadose supplement had no additional effect on the serum retinol levels of the children, although concentrations of retinol in the children rose in the first six months of life. This trial is registered with NCT00742937.
