1 · What the graph read from it

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.

2 · The registry

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

backgroundCoronavirus disease 2019 (COVID-19) during pregnancy is associated with increased disease severity and an increased risk of perinatal complications. However, few studies of pregnant women with COVID-19 have been conducted in Korea. The purpose of this study was to describe the clinical course and pregnancy outcomes of pregnant women admitted to our hospital with COVID-19 according to the severity. MATERIALS AND

methodsThis retrospective cohort study included women aged 18 years of age or older who were hospitalized in the Gachon University Gil Medical Center with COVID-19 during pregnancy between July 1, 2021 and January 31, 2022. COVID-19 severity was classified according to the "Criteria for severity classification by symptoms of COVID-19" presented by the Korea Disease Control and Prevention Agency. Severe cases were defined as those who required oxygen treatment administered via a high-flow nasal cannula or invasive mechanical ventilation or should be applied extracorporeal membrane oxygenation (ECMO) or continuous renal replacement therapy.

resultsA total of 103 pregnant women were hospitalized with COVID-19 during the study period. Their mean age was 33 (± 4.14) years, and 4 (3.9%) had been vaccinated against COVID-19. At the time of diagnosis of COVID-19, 3 (2.9%), 33 (32.0%), and 67 (65.1%) patients were in the first, second, and third trimester, respectively. The most common symptoms were cough (99 patients, 96.1%) and fever (85 patients, 82.5%). There was 1 (1.0%) asymptomatic patient. Forty patients (38.8%) required supplemental oxygen and 19 patients (18.4%) had severe disease. Of the 19 severe cases, 7 were in the 2nd trimester and 12 were in the 3rd trimester. Forty-one (39.8%) patients delivered, including two twin deliveries. Of the 41 cases of delivery, 14 were premature, 4 out of 21 (19.0%) in mild, 4 out of 12 (25.0%) in moderate, and 6 out of 8 (75.0%) in severe. Severe disease was associated with an increased rate of preterm birth (

conclusionPregnant women with COVID-19 had a high rate of severe disease and a high preterm delivery rate, especially among those with severe disease.
