Impact of obstetric and surgical factors on isthmocele development: insights from a prospective cohort study.

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
backgroundIsthmocele is a defect at the site of the cesarean section scar and is increasingly being recognized as a common complication following cesarean delivery. It may cause abnormal uterine bleeding, pelvic pain, and fertility issues. This study aimed to identify risk factors associated with isthmocele formation after the first cesarean section.
methodsThis prospective cohort study included 262 women aged 14-50 years who underwent their primary cesarean section at Arash Women's Hospital from 2021 to 2024. Previous cesarean deliveries, the history of myomectomy, repeated uterine curettage, and age outside the 14-50 years were exclusion criteria. Demographic, obstetric, surgical, and postoperative data were collected. A transvaginal ultrasound was used for the detection of an isthmocele. Univariate and multivariate logistic regression analyses were performed to identify associated factors with isthmocele formation.
resultsIsthmocele was detected in 19% (n = 50) of patients. Women with isthmocele had higher gestational age at delivery (39.2 ± 0.9 vs. 38.5 ± 1.7 weeks; p = 0.04), shorter delivery intervals (4.6 ± 1.3 vs. 5.2 ± 0.9 years; p = 0.01), more frequent retroverted uterus (28% vs. 11.3%; p = 0.003) and locking suture repair (20% vs. 7.1%; p = 0.005). In multivariable analysis, gestational age (OR = 1.71, 95% CI 1.19, 2.45) and retroverted uterus (OR = 2.82, 95% CI 1.25, 6.35) increased the odds of isthmocele, while longer inter-delivery intervals were protective (OR = 0.65, 95% CI 0.44, 0.97).
conclusionsIsthmocele is a frequent complication after primary cesarean section. Modifiable factors, such as the timing of delivery, management of infection, inter-pregnancy interval, and surgical technique, should be considered in reducing the risk.
