Sonographic Predictors and Long-Term Reproductive Outcomes in Recurrent Cesarean Scar Pregnancy: A Retrospective Cohort Study.
Article in Journal of ultrasound in medicine : official journal of the American Institute of Ultrasound in Medicine, 2026. 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
objectivesTo explore the ultrasound findings, treatment strategies, and reproductive outcomes in patients with recurrent cesarean scar pregnancy (CSP), providing evidence for clinical management.
methodsWe identified 1371 confirmed CSP from 1517 initially screened cases (2012-2022) through blinded image review. From 159 subsequent live births in this cohort, 27 recurrent CSP cases were matched 1:1 with CSP patients having normal subsequent pregnancies. Baseline characteristics and reproductive outcomes were collected via medical records and structured interviews.
resultsThis study revealed the recurrent CSP group showed significantly higher rates of exogenous implantation pattern (33.3% versus 7.4%, OR = 1.96), rich vascularity on color Doppler (81.5% versus 40.7%, OR = 2.80), and embryonic cardiac activity detection (51.9% versus 18.5%, OR = 1.98) than the normal intrauterine pregnancy group after CSP (p < .05) during initial diagnosis. The most commonly used treatment at our hospital is trans-abdominal ultrasound-guided suction curettage, which effectively controls the condition and preserves fertility. However, during long-term follow-up, some patients still face the risks of recurrence infertility.
conclusionsRecurrent CSP presents characteristic sonographic features at initial diagnosis, among which an exogenous implantation pattern, rich vascular flow signals, and embryonic cardiac activity serve as relevant and significant indicators. Although transabdominal ultrasound-guided suction curettage is effective in managing the condition and preserving fertility, some patients still face long-term risks of recurrence and infertility.
