Post-COVID-19 condition after SARS-CoV-2 infection during pregnancy: a population-based questionnaire cohort study.

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
Introduction: Post-COVID-19 condition encompasses various symptoms that can occur after the acute SARS-CoV-2 infection. The risk of developing symptoms of the post-COVID-19 condition is higher in women infected during pregnancy than in non-obstetric cohorts. Method: We conducted a nationwide, prospective, population-based cohort study based on questionnaire data investigating the extent of post-COVID-19 condition after SARS-CoV-2 infection during pregnancy and whether the condition was related to the trimester at infection or the severity of infection. All women with a positive SARS-CoV-2 test during pregnancy in Denmark between 1 March 2020 and 17 November 2021 were invited to participate by responding to an online questionnaire. Result: Overall, 2,406 women met our inclusion criteria and were invited to participate by receiving an online questionnaire. In total, 1,007 (41.9%) responded to the survey, and 920 (38.2%) completed ≥70% of the items in the questionnaire and were included in the analysis. In total, 636 (69.1%) experienced a symptom of post-COVID-19 condition at any given time after SARS-CoV-2 infection, and 465 (50.1%) had at least one symptom of post-COVID-19 condition lasting ≥8 weeks after primary infection with SARS-CoV-2. The most common symptoms were fatigue, a change in the sense of smell and taste, and hair loss. The onset of most symptoms was within the first 4 weeks after infection with SARS-CoV-2. The median duration of symptoms differed substantially, ranging from 4 to 40 weeks, with forgetfulness lasting the longest. Participants who experienced symptoms during their primary SARS-CoV-2 infection were more likely to report symptoms of post-COVID-19 condition. However, we found no association between disease severity or trimester of infection and subsequent post-COVID-19 condition. Conclusion: Half of the women with SARS-CoV-2 infection during pregnancy had symptoms of post-COVID-19 condition lasting ≥8 weeks. The likelihood of reporting symptoms of post-COVID-19 condition increased when having symptomatic SARS-CoV-2 infection during pregnancy. Nonetheless, we found no association between severe disease requiring hospital admission or the trimester of infection and the subsequent development of post-COVID-19 condition.
