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
Previous coronavirus epidemics were associated with increased maternal morbidity, mortality, and adverse obstetric outcomes. Reports for SARS-CoV-2 indicate that the obstetric population is at increased risk for severe illness, although there are still limited data on mild COVID-19 infection during pregnancy. To determine the association between mild COVID-19 infection during pregnancy, and maternal and neonatal outcomes, we performed a prospective cohort study among pregnant women with COVID-19 and a control group. Postnatal depressive symptoms were assessed using the Edinburgh Postnatal Depression Scale. We recruited 84 pregnant women with mild COVID-19 and 88 pregnant women without COVID-19. All participants were unvaccinated. The most common acute COVID-19 symptoms were headache (82.1%), loss of smell (81%), and asthenia (77.4%). The median duration of long COVID symptoms was 60 days (interquartile range, 130). Pregnant women with a COVID-19 diagnosis were at greater risk for obstetric ultrasound abnormalities-mainly, fetal growth restriction (relative risk [RR], 12.40; 95% CI, 1.66-92.5), premature birth (RR, 2.62; 95% CI, 1.07-6.43), and postpartum depression (RR, 2.28; 95% CI, 1.24-4.21). Our results alert clinicians to the consequences of COVID-19 during pregnancy, even in mild cases, given the increased risk of ultrasound abnormalities, premature birth, long COVID symptoms, and postpartum depression. National guidelines on preventive measures and treatments should be based on scientific evidence, including attention to the impact on health and family needs during and after the COVID-19 pandemic.
