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

backgroundVaginal microbiota dysbiosis has been associated with female reproductive health and infertility. This study aimed to compare vaginal microbiota profiles according to fertility and ovarian induction status among Thai women.

methodsIn this cross-sectional study, vaginal samples were collected from Thai reproductive-aged women during their periovulatory period. The 16 S rRNA gene was amplified and sequenced to ascertain the composition of the vaginal microbiota among 92 women (30 fertile and 62 infertile women). Vaginal microbiota profiles at the phylum and genus levels were compared among fertile women, infertile women before ovulation induction, and infertile women after ovulation induction.

resultsThe dominant vaginal microbial phyla across all groups were Firmicutes, Actinobacteria, Bacteroidetes, and Fusobacteria. Lactobacillus was the predominant genus across all groups. However, exploratory differential abundance analyses identified several differentially enriched taxa across fertile, infertile (pre-ovulation induction), and infertile (post-ovulation induction) groups. No significant differences in alpha or beta diversity were observed between groups.

conclusionOur findings did not demonstrate significant differences in overall vaginal microbial diversity between fertile and infertile Thai women. However, exploratory differential abundance analyses identified several taxa that may warrant further investigation. Larger prospective studies are needed to better clarify the potential role of vaginal microbiota in reproductive health and infertility.
