Fetal mortality before and during the COVID-19 pandemic: a single-center cohort study in Rio de Janeiro, Brazil.

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 aim of this study was to compare the characteristics of pregnancies that resulted in fetal death before and during the COVID-19 pandemic in a private maternity hospital in Rio de Janeiro, Brazil.
methodsThis retrospective cohort study considered all pregnancies that ended in fetal death in a private maternity hospital in Rio de Janeiro, Brazil, from January 2018 to December 2021. Maternal and fetal characteristics were compared between the periods before the pandemic and during the pandemic. Data were extracted from electronic medical records, and statistical analyses included Student's t-test, chi-square test, and Fisher's exact test where applicable.
resultsAmong 41,162 deliveries at Casa de Saúde Perinatal, 88 (0.21%) resulted in fetal death, with 38 (43.2%) occurring pre-pandemic (2018-March 2020) and 50 (56.8%) during the pandemic (March 2020-2021). Maternal demographics, comorbidities, and prepartum complications showed no statistically significant differences between groups. COVID-19 infection was identified in 12% of the pandemic-group pregnancies, but no significant disparities in fetal death causes or abnormalities were found.
conclusionsNo significant differences were observed in maternal or fetal characteristics, prepartum complications, or fetal mortality rates between the pre-pandemic and pandemic periods in this private hospital setting. However, this does not reflect the broader Brazilian healthcare reality, where disparities in access and resources may have influenced outcomes differently.
