Association between first-trimester subchorionic hematoma and pregnancy loss before 20 weeks of gestation in singleton pregnancies.
Article in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
To evaluate the association between a first-trimester subchorionic hematoma (SCH) and pregnancy loss before 20 weeks of gestation in singleton pregnancies. We conducted a retrospective cohort study of singleton pregnancies from January to December 2021. All patients had routine first-trimester ultrasound scans and were followed up for pregnancy outcomes. We compared pregnancy loss rates before 20 weeks in women with and without SCH and analyzed risk factors using logistic regression. Out of 1,144 singleton pregnancies, 559 (48.9%) had SCH. Women with SCH had higher rates of vaginal bleeding (38.1 vs. 23.2%, P < 0.001). SCH was independently associated with miscarriage before 20 weeks (adjusted OR 1.94, 95% CI 1.19-3.15). Earlier SCH diagnosis increased miscarriage risk (adjusted OR 2.71 for diagnosis before 7 weeks, 95% CI 1.45-5.07). SCH size was not linked to pregnancy loss, but "large" SCH increased placental abruption risk (adjusted OR 5.03, 95% CI 1.20-21.11). Dydrogesterone use appeared protective against miscarriage (adjusted OR 0.28, 95% CI 0.15-0.52). First-trimester SCH is associated with an increased risk of miscarriage before 20 weeks. Large SCHs increase the risk of placental abruption, while dydrogesterone use may reduce miscarriage risk.
