Effect of zinc supplementation on growth of low birth weight infants aged 1-6 mo in Ardabil, Iran.
Trial report in Indian journal of pediatrics, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 3 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
objectiveTo assess the effect of zinc supplementation on growth of low birth weight (LBW) infants aged 1-6 mo.
methodsLBW infants were enrolled at birth and randomly assigned to receive 5 mg elemental Zn per day (n = 45) or placebo (n = 45) until 6 mo of age. They were followed monthly for information on compliance; anthropometric measurements were performed monthly.
resultsAfter randomization, 5 infants from zinc group and 9 from placebo group were excluded. At 6 mo of age, significantly greater weight gains were observed in the zinc than in the placebo group (4995 ± 74 g in zinc group vs. 3896 ± 865 g in placebo group, p=0.036). Length gain during the study period improved in zinc group (16.9 ± 8.2 cm vs. 15.1 ± 4.1 cm, p=0.039); after zinc supplementation head circumference were increased (8.7 ± 1.4 cm vs. 7.4 ± 1.5 cm p < 0.001). In male infants, total weight gain and height and head circumference gain were higher in the zinc than in the placebo group. However, only head circumference change was statistically significant. A similar trend was observed among female infants, but these differences were not statistically significant. There was no significant relation between breast-feeding status and the main outcome variables.
conclusionsInfants in the present study showed improvements in growth rate, but more studies are required in this field to confirm this fact.
