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

purposeGestational diabetes mellitus (GDM) is one of the most common medical complications in pregnancy. This systematic review aimed to evaluate the association between vitamin E and GDM.

methodsRelevant articles from the Cochrane Library, PubMed, Scopus, Science Direct, Web of Science, and EMBASE databases up to December 2019 were searched. The inclusion criteria were observational full-text articles. The fixed and random effect models were used to analyze the pooled data using Review Manager 5.3.

resultsThirteen studies, including 596 participants, of whom 285 were diagnosed with GDM were included in the meta-analysis. The vitamin E level was significantly lower in women with GDM (MD: - 0.10; 95% CI: [-0.15, - 0.05]). The level of vitamin E was not different between overweight women with GDM and healthy pregnant women (MD: 0.03; 95% CI: [-0.08, 0.013]). The level of vitamin E was significantly lower in the third trimester of pregnancy in GDM women in comparison to the healthy pregnant women(MD: -0.09; 95% CI: [-0.12, -0.06]).

conclusionThis study showed that the level of vitamin E is significantly lower in GDM women compared to healthy pregnant women.
