Effects of the COVID-19 pandemic on maternal-fetal outcomes in a nonepidemic designated hospital: a retrospective study and clinical experience summary.
Article in BMC infectious diseases, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 assess the changes in maternal-fetal outcomes in a nonepidemic designated hospital during the COVID-19 pandemic.
methodsThis retrospective cohort study was conducted between January 1, 2019, and December 31, 2021 on pregnant patients. The fixed-effects regression model was used to determine changes in birth outcomes and pregnancy-related complications between three periods with the pre-epidemic cohort as the control group. Logistic regression was applied to determine the odds ratio (OR) for binary outcomes.
resultsThere were 15,261 births during the pre-epidemic period, and this number decreased by 15% and 23% to 12,980 and 11,736 in the first and second epidemic cohorts, respectively. The mean birth weight during the pre-epidemic period was 3319 which decreased to 3309 and 3272 g in the following periods. Excluding stillbirth and preterm, all other outcomes differed significantly between the three periods. Gestational diabetes mellitus (GDM) (17-19%) and maternal hypertension (9.2-11%) appeared to increase. Compared to the pre-epidemic period, the odds of macrosomia and LGA significantly decreased in the second epidemic cohort (adjusted ORs: 0.76 and 0.8), while the odds of low birth weight (LBW) and small gestation age (SGA) increased (ORs: 1.25 and 1.16). The odds of neonatal asphyxia (OR: 1.4), and hypertension (OR: 1.29) appeared to increase in the second epidemic cohort, while GDM decreased in the first cohort (OR: 0.88) and increased in the second cohort (OR: 1.15). Vaginal delivery underwent a marginal decrease in both the first and second epidemic cohorts (ORs: 0.89 and 0.92).
conclusionThe COVID-19 pandemic may have had a substantial and long-term impact on non-infected pregnant women and newborns. Our research results provided precious research information and clinical experience summary for population health research in the future.
