Managing Ectopic Pregnancies by Targeting Chorionic Villi with a Transvaginal Injection of Ethanol into the Lacunar Space.
Article in Biomedicines, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Methotrexate has been the main mode of non-surgical treatment for ectopic pregnancies. However, we have developed an easier, repeatable method that can be applied even to patients with a high beta-human chorionic gonadotropin (β-hCG) level and/or positive fetal heartbeat, by targeting chorionic villi with a transvaginal injection of absolute ethanol (AE) into the lacunar space (intervillous space). The efficacy and safety of this method were examined in 242 cases of ectopic pregnancy, including 103 with positive fetal heartbeat. Serum β-hCG level was measured at frequent intervals, and transvaginal ultrasonography was performed to observe the gestational sac and hyperechoic inner ring. Of the 242 patients, 222 (91.7%) were successfully treated. The average number of AE injection(s) required was 1.6 (range: 1-5), and the average dose was 3.2 mL. After the treatment, many of the patients tried to conceive again, and 63 of the traceable 145 patients (43.4%), who had fallopian tube pregnancy, and 7 of the traceable 12 patients (58.3%), who had cervical or cesarean scar pregnancies, successfully conceived and delivered babies with no observed side effects. Therefore, this method could be an effective treatment for ectopic pregnancy with the potential to replace conventional surgical interventions and medical treatment using methotrexate.
