Assessment of the factors associated with initial treatment failure in cesarean scar pregnancy: A retrospective case-control study.
Article 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
This study identified factors associated with initial treatment failure in cesarean scar pregnancy (CSP) and provided insights to improve management strategies and patient outcomes. This retrospective study involved 451 electronic medical records of patients with CSP who were treated between January 2017 and June 2024, of whom 76 experienced initial treatment failure and 375 achieved initial treatment success at our hospital. Multiple logistic regression analyses were performed to identify risk factors for initial treatment failure. The failure rate of ultrasound-guided evacuation was significantly higher than that of hysteroscopy-guided evacuation, vaginal excision of CSP lesions, and laparoscopic excision of CSP lesions (P < .001). Multiple logistic regression analysis revealed that independent risk factors for initial treatment failure in CSP patients included baseline serum β-human chorionic gonadotropin (β-hCG) (odds ratio (OR) = 2.361, 95% confidence interval (CI) = 1.108-5.029, P = .026), initial treatments (OR = 0.632, 95% CI = 0.486-0.823, P = .001), gestational age (OR = 2.413, 95% CI = 1.319-4.415, P = .004), gestational sac diameter (OR = 3.104, 95% CI = 1.492-6.456, P = .002), and cesarean scar (CS) myometrial thickness measurement (OR = 0.233, 95% CI = 0.072-0.755, P = .015). In conclusion, these findings indicate that ultrasound-guided evacuation is an independent risk factor for initial treatment failure. Therefore, individualized treatment selection for CSP should be based on baseline serum β-hCG levels, gestational age, gestational sac diameter, CS myometrial thickness measurement, and treatment modality. Additional evaluation may be necessary before proceeding with ultrasound-guided evacuation in patients presenting with multiple risk factors for treatment failure.
