Ovarian Tumors during Pregnancy and Adverse Pregnancy Outcome: A Retrospective Analysis.
Article in Asian Pacific journal of cancer prevention : APJCP, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveTo determine the prevalence of ovarian tumor in pregnancy. MATERIALS AND
methodsA retrospective descriptive study was conducted using electronic data from Obstetrics and Gynecology Department at Bhumibol Adulyadej Hospital (BAH), Royal Thai Air Force, Thailand recorded between January 2012 and December 2022. The participants were patients diagnosed with ovarian tumors during pregnancy (OTP) within the study period. Demographic characteristics, histopathological findings, ultrasonography results and pregnancy outcomes were recorded.
resultsA total of 190 OTP cases were identified among 41,842 pregnant women. One hundred twenty-six OTP cases underwent surgery during pregnancy. The mean age of the participants was 29.6 years. The prevalence of ovarian tumors was 4.5(190/41,842) in 1000 pregnancies. Malignant ovarian tumors accounted for 0.14% (2/126). Histopathological analysis revealed that germ cell ovarian tumors and common epithelial ovarian tumors were found in 50.79% (64/126) and 49.2% (62/126) of cases, respectively. Most germ cell ovarian tumors were mature cystic teratomas, which were found in 98% (63/64) of cases. One-third (32/126) of the OTP cases underwent surgery during the second and early third trimesters. Fetal loss following surgery occurred in 18.75% (6/32) of cases. Adnexectomy performed with cesarean delivery and after vaginal delivery occurred in 93 and 1 cases, respectively. Symptomatic OTP leading to emergency surgery was observed in 6.84% (13/190) of cases.
conclusionThe prevalence of OTP was 4.5 per 1,000 pregnant women. Fetal loss during surgery in pregnancy occurred in 18.75%. Mature cystic teratoma was the common histopathological finding.
