Placenta accreta and uterine arteriovenous malformation following medically treated missed abortion in patient with undiagnosed cesarean scar pregnancy.

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
Cesarean scar pregnancy (CSP) is a rare condition, accounting for 6% of ectopic pregnancies, with a rising incidence. If not diagnosed early, it may lead to severe complications such as hemorrhage, need for surgery, placenta accreta, and arteriovenous malformation (AVM). Treatment consists of expectant management, medical, or surgical regiments. A 31-year-old woman (G3P2) with one previous cesarean section presented for early pregnancy evaluation. Ultrasound initially showed an intrauterine pregnancy, but follow-up confirmed a missed abortion, and mifepristone/misoprostol regimen was initiated. At follow-up, persistent tissue at the cesarean scar raised suspicion of scar pregnancy. Declining human chorionic gonadotropin levels were noted, and expectant management implemented. Increased bleeding led to ultrasound and magnetic resonance imaging, revealing a 10 cm tumor suspicious of AVM. Fertility-preserving surgery with laparoscopic 'niche' resection technique was pursued, but hysterectomy was ultimately required. Histopathological examination showed placenta accreta. Early diagnosis and management of CSP are essential to reduce serious complications.
