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
backgroundPlacenta accreta spectrum (PAS) is a life-threatening condition often managed by cesarean hysterectomy, resulting in numerous negative impacts on women's health. Most PAS cases do not involve parametrial invasion and may not require aggressive or complex surgical approaches. However, no simplified uterus-sparing technique exists for this subgroup. Therefore, we developed a novel surgical approach, "Simple Conservative surgical Approach for Placenta Accreta Spectrum - SCAPAS," tailored for PAS without parametrial invasion. SCAPAS included eight main steps.
objectivesTo evaluate the efficacy and safety of SCAPAS in conservative surgical management of women with PAS without parametrial invasion. STUDY
designThis prospective study was conducted from January 2022 to June 2023 at Hanoi Obstetrics and Gynecology Hospital. Sixty-three women with PAS without suspected parametrial invasion, according to the prenatal ultrasound staging system for PAS disorder, underwent elective cesarean delivery using the SCAPAS technique at ≥35 weeks of gestation. Maternal and fetal outcomes were collected. Successful cases were defined as those achieved uterine conservation following SCAPAS without any life-threatening complications.
resultsOf the 63 cases, 74.6% were patients under 35, and 66.7% had a history of two or more cesarean sections. The majority of women were diagnosed with PAS2 (69.8%). The success rate of SCAPAS was 85.7%. Success rates for placenta accreta, increta, and percreta were 100%, 82.4%, and 81.8%, respectively. The overall median intraoperative blood loss was 1200 mL (range 400-2500 mL), and the median duration of surgery was 80 minutes (range 35-124 minutes), with a mean interval from skin incision to fetal delivery was 30 minutes. Bladder injury and mild wound infections occurred in 6.3% (4/63) and 4.8% (3/63) cases, respectively. No patient required re-laparotomy. Total 20.6% of newborns had an Apgar score of less than 7 at 1 minute, but all recovered after 5 minutes.
conclusionsSCAPAS is a simple, safe, and effective surgical approach for conservative management of PAS without suspected parametrial invasion. Further studies are needed to develop a preoperative classification based on location, area, and degree of invasion to improve outcomes in PAS patients.
