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

objectiveTo systematically review the impact of vaginal delivery (VD), cesarean scar (CS), cesarean scar disorder (CSD) and intra-cavitary fluid (ICF) on the reproductive outcomes of women involving assisted reproductive technology (ART) based on Bayesian network meta-analysis.

methodsSix databases were searched from the inception to October 16, 2024. Primary outcomes were clinical pregnancy rate and live birth rate. Secondary outcomes included positive human chorionic gonadotropin (hCG) test rate, miscarriage rate, ectopic pregnancy rate, and severe adverse pregnancy outcomes. Extracted study data were analyzed by pairwise and network meta-analysis using R software and Stata.

resultsThis study revealed that CS, CSD and ICF significantly reduced clinical pregnancy rate (CS vs VD: RR = 0.88, 95% CI 0.78-0.99,

conclusionsICF, CSD, and CS all significantly reduce clinical pregnancy rate and live birth rate in women with ART. CSD and ICF had much lower live birth rate than CS. Notably, ICF was a prominent risk factor for these adverse reproductive outcomes.
