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

objectiveTo evaluate the prevalence of preeclampsia among cases of COVID-19 infection during pregnancy and the association between both conditions, in a multicenter cohort of Brazilian women with respiratory symptoms. STUDY

designAncillary analysis of the Brazilian Network of COVID-19 in Obstetrics (REBRACO) study. We performed a nested case-control analysis selecting all women with COVID-19 and compared outcomes between women with and without PE. MAIN OUTCOMES: Maternal, gestational, and clinical characteristics and perinatal outcomes. MEASURES: Prevalence ratio (PR) and its 95%CI for each of the predictors and outcomes.

resultsA total of 203 women were included: 21 (10.3%) in PE group and 182 (89.7%) in non-PE group. Preeclampsia was not different among women with and without COVID-19 (10.3% vs 13.1%, p-value = 0.41), neither complication such as eclampsia and HELLP syndrome. Chronic hypertension (33.4%) (p < 0.01) and obesity (60.0%) (p = 0.03) were the most frequent comorbidities in PE group, and they were significantly more frequent in this group. Women with PE had more cesarean section (RR 5.54 [1.33 - 23.14]) and their neonates were more frequently admitted to neonatal intensive care unit (PR 2.46[1.06 - 5.69]), most likely due to preterm-birth-related complications.

conclusionThe prevalence of PE among women with COVID-19 infection during pregnancy was around 10%; women with COVID-19 and a history of chronic hypertension or obesity are more likely to have preeclampsia. Cesarean section is increased among women with PE and COVID-19, with increased rates of neonatal admission to intensive care units, mostly due to prematurity.
