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

backgroundEndometriosis is a benign, chronic, gynecological disease which affect the women in reproductive age. The dysfunction of immune system is associated with endometriosis and the diversity of microbiota in genital tract. According to previous studies, microbiota significantly contributes to multi-systemic function, but the evidence of relationship between microbiota and endometriosis remains insufficient.

methodsThere are 68 participants were included in this study and 134 samples obtained from the cervical canal, posterior fornix and uterine cavity were analyzed by 16s-rRNA sequencing. The raw data was filtered, analyzed, and visualized, and bio-information methods were used to identify the characteristics of microbiota.

resultsTwo different locations near the cervix, cervical canal, and posterior fornix, exhibited no differences in alpha diversity. The microbiota profile of adenomyosis with endometriosis patients is different from control group through PCoA. Among the different disease groups, five microbiotas were distinctive in the genus level, and
