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

objectivePrenatal folic acid supplementation or maternal folate sufficiency may protect the offspring from obesity and insulin resistance. This study aims to summarize the findings of association between prenatal folic acid supplementation/maternal folate sufficiency and obesity/insulin resistance in the offspring.

methodsTwelve databases were searched for both published and unpublished work of prenatal folic acid supplementation/maternal folate status up to 1 July 2014. Experimental and observational studies on animals and human beings were included based on the eligibility criteria. There were no limits to the time period and language of publication. The study quality was assessed with a 10-Point Scale for Scientific Methodology.

resultsThe search identified 2548 records. Nine animal studies and five human studies satisfied search criteria were included. Five of these nine animal studies showed a protective effect of folic acid. Of the five human studies, one showed a protective effect of folic acid, two showed a harmful effect and two showed uncertain results.

conclusionsData from both animal studies and human studies are inconsistent. Future researches with sophisticated designs are needed to demonstrate the potential protective effect of maternal folate on obesity/insulin resistance in the offspring in animal models and human pregnancies.
