Association between the proportion of subchorionic hematoma within the gestational sac and miscarriage rate in IVF/ICSI patients.
Article in Frontiers in medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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: The main objective of this study was to summarize and analyze the pregnancy outcomes in the assisted reproductive technology (ART) population with subchorionic hematoma (SCH) in the first trimester. Moreover, we aimed to explore the risk factors for adverse pregnancy outcomes in patients with SCH. Methods: A retrospective cohort study was conducted on Results: After appropriate screening, 275 patients with SCH and 336 patients without SCH were enrolled. Patients with SCH had a significantly higher miscarriage rate than patients without SCH (13.5% vs. 8.3%, Conclusion: SCH increased miscarriage rate in the ART population. Patients with SCH combined with miscarriages had more embryos transferred, earlier detection of SCH, and smaller GS areas when SCH was first detected. Multivariate logistic regression analysis showed that the SCH proportion in the GS was a statistically significant risk factor for SCH associated with miscarriage. The miscarriage rate increased progressively with the SCH proportion in the GS.
