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: To explore the incidence of subchorionic hematoma (SCH) in IVF-ET ( Methods: This is a retrospective cohort study. Patients were included: IVF-fresh ET, IVF-FET, PGT-FET, AIH, and NP patient groups. The incidence of SCH in different ART and effect of SCH on pregnancy outcome were compared, Further, multivariate analyses of the occurrence of SCH were conducted. Results: The incidence of SCH with IVF-fresh ET, IVF-FET, PGT-FET, AIH and NP was 27.50%, 22.56%, 16.86%, 12.95%, and 13.02%, respectively. Compared with the incidences of SCH with AIH and NP that for IVF-fresh ET and IVF-FET transfer were significantly increased ( Conclusion: The incidence of SCH in ET was increased compared with that in the Not ET groups, especially after fresh ET. ET unavoidably seems to contribute to the development of SCH; however, it does not affect the pregnancy outcome.
