The influence of COVID-19 pandemic on intrauterine fetal demise and possible vertical transmission of SARS-CoV-2.
Article in Taiwanese journal of obstetrics & gynecology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectiveThe impact of COVID-19 on intrauterine fetal demise (IUFD) and vertical transmission of the SARS-CoV-2 from the mother to the fetus are crucial issues of the COVID-19 pandemic. In the current study, we aimed to detect the pandemic's influence on the IUFD and evaluate the vertical transmission of the SARS-CoV-2 through analysis of placental tissues collected from PCR positive women with IUFD above 20 weeks of gestation. MATERIALS AND
methodsThe pregnant women above 20 weeks of gestation and had a fetus intrauterine demised during pandemic were included in the study. The pregnant women screened for COVID-19. Vertical transmission searched from placental tissues of COVID-19 positive women by RT-PCR tests for the presence of SARS-CoV-2 RNA. The number of IUFD before the pandemic and during the pandemic compared to assess the influence of the COVID-19 pandemic on the IUFD ratio.
resultsAmong 138 pregnant women with IUFD, 100 of them could screen for COVID-19 status. RT-PCR test results of 6 of the screened pregnant women were positive for SARS-CoV-2. Placental tissues of these six women were analyzed, and one test result was positive for SARS-CoV-2 RNA. The IUFD ratio was significantly increased during the pandemic.
conclusionIt is clear that COVID-19 increases the IUFD ratio. Previous data for vertical transmission of SARS-CoV-2 during the second trimester is limited. We present the third case of literature that has positive placental results for SARS-CoV-2 RNA in the second trimester of pregnancy.
