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

backgroundBesides reducing the quality of obstetric care, the direct impact of COVID-19 on pregnancy and postpartum is uncertain.

objectiveTo evaluate the characteristics of pregnant women who died due to COVID-19. SEARCH STRATEGY: Cochrane Library, Embase, MEDLINE, Scopus, and Google Scholar were searched from inception to February 2021. SELECTION CRITERIA: Studies that compared deceased and survived pregnant women with COVID-19. DATA COLLECTION AND ANALYSIS: Relevant data were extracted and tabulated. The primary outcome was maternal co-morbidity. MAIN

resultsThirteen studies with 154 deceased patients were included. Obesity doubled the risk of death (relative risk [RR] 2.48, 95% confidence interval [CI] 1.41-4.36, I

conclusionCOVID-19 with at least one co-morbidity increases risk of intensive care and mortality.
