A prospective cohort study of pregnancy outcomes following antepartum infection with SARS-CoV-2.
Article in Pregnancy hypertension, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectivesOur study aimed to explore the impact of COVID-19 infection on pregnancy outcomes, accounting for the progression of variants, vaccines, and treatment modalities. STUDY
designWe performed a prospective longitudinal cohort study at two urban tertiary centers enrolling patients with a confirmed intrauterine singleton pregnancy from December 23, 2020 to July 18, 2022. Patients were evaluated for SARS-CoV-2 infection at enrollment and every trimester using serum antibody testing. The primary outcome was preterm birth. Symptom and treatment data were collected from pregnant patients with COVID-19 infections. Variant strain infection status was determined from local wastewater analysis.
results448 patients were enrolled, and 390 patients were retained through delivery with 159 unexposed and 231 exposed patients, of whom 56 patients (26.0 %) crossed over after enrollment to the exposed cohorts during pregnancy. There was no difference in rates of preterm birth between exposed and unexposed cohorts (14.6 % vs 11.3 %), in deliveries < 34 weeks (1.5 % vs 2.7 %), PPROM, (0.4 % vs 1.3 %), or gestational age at delivery (38.1 vs 38.2). Exposed patients were significantly more likely to be diagnosed with a hypertensive disorder (aOR 2.3, 95 % CI 1.2-4.1), specifically gestational hypertension (aOR 2.8, 95 % CI 1.3--6.0), but not preeclampsia/eclampsia. There were no differences in individual or composite neonatal outcomes.
conclusionsOur study contributed to the understanding of the effects of SARS-CoV-2 infection on pregnancy outcomes, with increased risk of hypertensive disorders of pregnancy but overall, no differences in adverse neonatal outcomes. Regular antenatal PCR and antibody screening allowed for higher detection and inclusion of patients with asymptomatic SARS-CoV-2 infection and effects on maternal and neonatal outcomes.
