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
introductionThe clinical treatment is complicated for patients with placenta previa who must terminate pregnancy due to fetal malformation, death, or inevitable abortion in the second trimester. It is difficult to manage excessive bleeding during pregnancy termination; and those patients face risks of removing the uterus, infection and other complications. PATIENT CONCERNS: Two patients had placenta previa in the second trimester. Both cases had to terminate pregnancy. Case 1 patient had intrauterine fetal death. Case 2 patient had life-threatening vaginal bleeding. Both patients had bleeding and their cervix was not mature during vaginal delivery. DIAGNOSIS: After hospitalization, placenta previa was confirmed by magnetic resonance imaging for case 1 patient. Placenta previa was confirmed by ultrasound examination for case 2 patient. Both patients had to terminate pregnancy.
interventionsWe designed a new procedure using a cervical ripening balloon to reduce the risks during pregnancy termination for patients with placenta previa. A cervical ripening balloon was inserted through the placenta and placed between the fetus and placenta; external force was applied to keep the cervical ripening balloon pressing against the placenta that covers the cervical os. The cervical ripening balloon dilated the cervix, quickly reduced bleeding, and induced vaginal delivery during pregnancy termination for patients with placenta previa. This method was applied to 2 patients with placenta previa who must terminate pregnancy. OUTCOMES: Using the new method, both patients had a successful pregnancy termination and vaginal delivery with minimal bleeding. Total time from the balloon placement to the end of the delivery was about 3 hours. The procedure only used a cervical ripening balloon without uterine artery embolization needed. The fetus was delivered through the vagina; and the uterus was fully retained. There was no postpartum infection.
conclusionThis new method using a cervical ripening balloon could be a quick and effective way to reduce the risks during pregnancy termination for patients with placenta previa. It is especially helpful in emergency situations with minimal requirements of personnel and equipment. Our study showed great potential of this new utilization of a cervical ripening balloon, and is worthy of further research.
