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

backgroundCurrent evidence concerning the association between persistent organic pollutants (POPs) and polycystic ovary syndrome (PCOS) is inconsistent. The aim of the present systematic review and meta-analysis is to evaluate the role of POPs in PCOS.

methodsDatabases including PubMed, Embase, Web of Science, and CNKI will be searched to identify qualified studies. All qualified studies regarding the association between POPs and PCOS will be included. The primary outcome of the present study is POPs levels in serum of subjects. Pooled analysis with corresponding 95% confidence intervals will be performed.

resultsThe comprehensive analysis and quantitative assessment will provide a better understanding of POPs concentrations in patients with PCOS.

conclusionThis meta-analysis and systematic review will generate evidence of the association between POPs and PCOS. PROSPERO REGISTRATION NUMBER: PROSPERO CRD42019126373.
