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

Group B Streptococcus (GBS) colonization during pregnancy is a major cause of neonatal infection, yet its microbial determinants remain unclear. This pilot study compared the vaginal and gut microbiota of late-pregnancy women with and without GBS colonization to explore potential microbial cues for peripartum risk stratification. Forty-three Japanese pregnant women (GBS-Negative = 34; GBS-Positive = 9) were enrolled at 35-37 weeks of gestation. Vaginal secretions and stool were analyzed by 16S rRNA (V3-V4) sequencing using QIIME 2 with SILVA annotation and community state type (CST) classification. Vaginal communities were mainly Lactobacillus-dominant. GBS-Positive women showed a non-significant tendency toward more
