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

purposeThe aim of this study was to investigate the correlation between the thickness of meconium-stained amniotic fluid (MSAF) and maternal infectious morbidity.

methodsA retrospective study of 15,950 term singleton pregnancies at a tertiary hospital (2020-2024). Women were categorized into four groups based on the presence and thickness of MSAF: clear, light, intermediate, and thick. The co-primary outcomes were clinical chorioamnionitis and puerperal endometritis, defined as a composite maternal infectious morbidity. In women with intrapartum fever (IPF), chorioamniotic swabs were obtained and compared according MSAF thickness. Multivariate analysis identified predictors of a composite maternal infections and adverse neonatal outcomes.

resultsOf the cohort, 13,745 had clear amniotic fluid, and 2,205 had MSAF (561 light, 1,426 intermediate, 218 thick). The incidence of maternal infections increased with MSAF thickness, with thick MSAF showing the highest rates of clinical chorioamnionitis (4.1%, p < 0.001) and endometritis (1.4%, p = 0.039). In IPF cases, thicker MSAF was associated with a higher prevalence of positive swab cultures, particularly of Enterobacteriaceae (61.9%). Group B Streptococcus (GBS) remained consistent across all MSAF groups. Multivariate analysis showed that MSAF levels were associated with increased maternal infectious morbidity (p < 0.001). Additional risk factors for maternal infections included nulliparity (p < 0.001), catheter balloon insertion (p = 0.004), prolonged ROM (p < 0.001), and cesarean delivery (p < 0.001). In contrast, only intermediate (p < 0.001) and thick MSAF (p < 0.001) correlated with adverse neonatal outcomes.

conclusionGreater severity of MSAF is associated with increased maternal infectious morbidity, especially infections related to Enterobacteriaceae. Studies about preventive measures in cases of thick MSAF are warranted.
