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 compare spontaneous preterm birth (SPTB) and iatrogenic preterm birth (IPTB) rates during both waves of the coronavirus disease 2019 (COVID-19) pandemic.

methodsRetrospective analysis of the PregCovid registry of pregnant women with COVID-19 was performed at a dedicated COVID-19 hospital in Mumbai, India. The data of 1630 women were analyzed for this study between April 4, 2020 and July 4, 2021. Prepandemic data were analyzed and compared with pandemic data. Main outcome measure was spontaneous preterm birth rate.

resultsPreterm deliveries were higher during the second wave (46/329; 14%) compared with the first wave (82/807; 10.2%) of the COVID-19 pandemic (P = 0.065). Higher SPTBs were reported during the second wave than the first wave (12.5% versus 8.3%) (P = 0.03) as well as the prepandemic period (12.5% versus 10.5%) (P = 0.286). IPTBs were significantly lower in the pandemic period than in the prepandemic period (1.8 versus 3.3) (P = 0.012).

conclusionIn Mumbai, India, we found an unusual change in SPTBs during the 6 months of the second wave of COVID-19 compared with the previous 10 months of the first wave of pandemic and 1 year of prepandemic.
