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

backgroundSeveral studies have assessed potential associations between use of weight loss products in the periconceptional period and neural tube defects (NTDs). However, the individual studies are inconclusive and there has not been a systematic review of this literature.

methodsWe conducted a systematic search, using Ovid MEDLINE and PubMed, to identify studies that evaluated the association between products used for weight loss and the risk of NTDs. Because many studies of birth defects only evaluate a composite birth defect outcome, we evaluated studies that defined the outcome as "any major birth defect" or as NTDs. We abstracted data on study design, exposure definition, outcome definition, covariates and effect size estimates from each article that met our inclusion criteria. For studies that evaluated a composite birth defect outcome, we also abstracted the number of NTD cases included in the composite outcome. We used a modified version of the Newcastle-Ottawa Scale to assess the quality of each article.

resultsWe screened 865 citations and identified nine articles that met our inclusion criteria. The majority of studies reported positive associations between maternal use of weight loss products and birth defects (overall and NTDs). However, there were few significant associations and there was considerable heterogeneity in the specific exposures assessed across the nine studies.

conclusionOur systematic review of weight loss products and NTDs indicates that the literature on this topic is sparse. Because several studies reported modest, positive associations between risk and use of weight loss products, additional studies are warranted.
