Clinical analyses of 66 cases of mid-trimester pregnancy termination in women with prior cesarean.

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
backgroundThe rate of cesarean delivery has significantly increased in China in the last decade. Women with prior cesarean history tend to have a higher risk of uterine rupture during termination of the pregnancy in mid-trimester than those without such a history. The aim of our study was to evaluate the influences of the potential risk factors on uterine rupture in women with prior cesarean.
methodsWe conducted this retrospective study of women with prior cesarean section, who underwent mid-trimester pregnancy termination between January 2006 and December 2013 in Peking Union Medical College Hospital. The protocol was oral administration of mifepristone and misoprostol for the patients with the gestational ages below 16 weeks or intra-amniotic injection of ethacridine lactate (EL) for those with at least 16 weeks of gestational ages. The thickness of the lower uterine segment (LUS) was measured before the termination of pregnancy. Logistic regression was used to study the risk factors of uterine rupture.
resultsThe total rate of successful abortion was 93.9% (62/66). Four patients failed in induction, and one of them received curettage, whereas the other three experienced uterine rupture (4.5%). The successful rates of abortion were 85.7% (30/35) for women treated with mifepristone-misoprostol and 86.1% (31/36) for those treated with EL. There was a significant difference in the mean LUS thickness between the uterine rupture group (3.0 ± 2.0 mm) and the nonrupture group (7.0 ± 3.0 mm) (P < 0.05). The LUS thickness of <3 mm was associated with uterine rupture during mid-trimester pregnancy termination in women with prior cesarean (odds ratio, 94.0; 95% confidence interval 4.2-2106.1) after adjusted maternal age, gestational age, interdelivery interval and prior cesarean section. Severe bleeding that required transfusion occurred in one case (1.5%).
conclusionsBoth the mifepristone-misoprostol and the EL regimens were effective and safe for the termination of mid-trimester pregnancy in women with prior cesarean. A thinner LUS is associated with a relatively high risk of uterine rupture.
