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
Background: During the COVID-19 pandemic, some jurisdictions used universal screening for SARS-CoV-2 infection at obstetrical units. This study evaluated the utility of this screening strategy. Methods: We assessed the asymptomatic infection rate and test positivity rate at six obstetrical units in Quebec, Canada. Results: 32,663 parturients were admitted to the six obstetrical units, of which 77.5% were tested for SARS-CoV-2 on admission. Among all six sites, 388 parturients (1.2% [95% CI 1.07% to 1.31%]) tested positive for SARS-CoV-2. Of these, 74.2% were asymptomatic. Rates of positive asymptomatic admissions were similar across sites, ranging from 0.5% to 1.3%. Test positivity rates among parturients varied across the pandemic, ranging from 0.0% to 9.0%. Three nosocomial SARS-CoV-2 infections occurred, with two occurring at the same site. Conclusions: Non-universal strategies such as symptom-based screening and personal protective equipment may be more practical and cost effective for future respiratory pandemics.
