1 · What the graph read from 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.

2 · The registry

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

backgroundIncreased requirement and decreased dietary intakes of micronutrients during pregnancy might affect maternal health and pregnancy outcomes. This study was aimed to examine the effects of two types of multiple micronutrient supplementations on pregnancy outcomes in Kashan, Iran.

methodsIn a randomized single-blind controlled clinical trial, 104 primigravid singleton pregnant women aged 18-30 years were randomly assigned to receive either a multivitamin (n = 51) or a multivitamin-mineral (n = 53) supplements for 20 weeks. Participants consumed supplements once a day at week 16 of gestation. Maternal anthropometric data as well as newborn's weight, height, head circumference and 5-min Apgar score were also determined. Independent samples t-test was used for comparing between-group means. Multivariate linear regression analysis was used to identify determinants of newborn's weight, height and head circumference.

resultsWomen taking multivitamin-mineral supplements gained marginally less weight until week 28 than those taking multivitamin supplements (weight at week 28 of gestation: 67.5 ± 11.4 vs. 71.6 ± 10.3 kg, P = 0.06). Mean body mass index at week 28 (25.8 ± 4.0 vs. 28.4 ± 3.7 kg/m(2), P = 0.001) as well as at delivery (28.0 ± 3.9 vs. 30.1 ± 3.8 kg/m(2), P = 0.006) was lower among women taking multivitamin-mineral supplements than those taking multivitamin supplements. Although no significant difference was seen in newborns' height and Apgar score between the two groups, mean birth weight (3.3 ± 0.4 vs. 3.1 ± 0.4 kg, P = 0.04) and head circumference (35 ± 1.4 vs. 34 ± 1.3 cm, P < 0.0001) of the infants whose mothers receiving multivitamin-mineral supplements were higher than those whose mothers received multivitamins. Multivitamin-mineral use by pregnant women was a significant predictor of infants' weight (β =0.191, P = 0.03) and head circumference (β =0.907, P = 0.005).

conclusionsIn conclusion, we found that birth weight and head circumference was increased in infants whose mothers received multivitamin-mineral supplements for 5 months during pregnancy compared with infants whose mothers received multivitamin supplements.
