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

Background: Bacterial infection at the maternal-fetal interface contributes to adverse pregnancy outcomes, including preterm birth, chorioamnionitis, and sepsis. Despite evolving obstetric practices that may influence microbial patterns, recommended clinical algorithms for prophylaxis and treatment rely on outdated data. Furthermore, the pathogenic organisms associated with adverse outcomes remain incompletely characterized. Methods: We conducted a retrospective study of placental cultures from a high-risk obstetric cohort from a single hospital system between 2014 and 2019 (n = 714). Placental cultures were obtained from deliveries at high risk for infection: (eg, preterm birth or suspected chorioamnionitis). Placental cultures were stratified into pathogenic and nonpathogenic. Associated clinical outcomes, histopathology, and antimicrobial susceptibility patterns were compared. Results: Pathogenic organisms were identified in 69% of cultures (492 of 714). Group B Conclusions: Bacterial pathogens isolated from the placenta in high-risk pregnancies are associated with perinatal morbidity. Group B
