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

According to research, intrauterine exposure to non-pathogenic maternal microorganisms during pregnancy is influenced by the mother's nutritional, metabolic, and immunological status. This study investigates the association between maternal gut microbiota composition, fetal development, and neonatal microbiota, with the aim of exploring their interconnected health dynamics. A cohort-based correlational study was conducted involving 114 women (≥18 years old, ≤12 weeks of gestation) attending prenatal consultations at the ISSSTE General Hospital in Pachuca de Soto, Hidalgo, México. Data were collected at four stages: before 11 weeks, at 11-14 weeks, at 20-24 weeks, and at 31 weeks of pregnancy. Assessments included anthropometric measurements, biochemical markers, and intestinal microbiota analysis. The Firmicutes/Bacteroidetes (F/B) ratio positively correlated with venous duct flow and expected weight for gestational week (r = 0.02272,
