The impact of home fortification with multiple micronutrient powder on vitamin A status in young children: A multicenter pragmatic controlled trial in Brazil.
Trial report in Maternal & child nutrition, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 2 of them syntheses 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
Home fortification with multiple micronutrient powder (MNP) is effective in the prevention of anemia in young children. However, the impact on their vitamin A status remains controversial. This study aimed to evaluate the effect of MNP on vitamin A status in young Brazilian children. A multicenter pragmatic, controlled trial was carried out in primary health centers in four Brazilian cities. In the beginning of the study, the control group (CG) consisted of children 11-14 months old (n = 395) attending in routine pediatric health care. In parallel, the intervention group (IG) was composed of children 6-8 months old (n = 399), in the same health centers, who followed the intervention with MNP for 2-3 months. The analysis of the effect of MNP on vitamin A status was performed by comparing the IG with the CG after a 4- to 6-month follow-up when IG children had reached the age of the controls. The prevalence of vitamin A deficiency (VAD; serum retinol <0.70 μmol/L) in the CG was 16.2%, while in the IG was 7.5%-a 55% reduction in the VAD [prevalence ratio (95% confidence interval) = 0.45 (0.28; 0.72)]. This reduction was also significant when stratifying the study centers by coverage of the Brazilian Vitamin A Supplementation Program. The adjusted mean of vitamin A serum concentrations improved in the IG compared with CG children, with a shift to the right in the vitamin A distribution. Home fortification with MNP was effective in reducing VAD among young Brazilian children.
