Prevalence of olfactory dysfunction among postpartum women and impact of SARS-CoV-2 infection during pregnancy.

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
Olfactory dysfunction resulting from COVID-19 has imparted a lasting impact on olfaction among the general public, including pregnant women contracting SARS-CoV-2 infection. While olfactory dysfunction can impact physical, mental, and psychosocial well-being, there has been little research on olfaction during pregnancy and postpartum, nor the impact of SARS-CoV-2 infection on olfaction while pregnant. Therefore, the primary study aims are to evaluate olfaction in the postpartum period and determine the impact of antecedent SARS-CoV-2 infection. We recruited two cohorts of postpartum women, those with a history of SARS-CoV-2 infection before or during pregnancy (COVID cohort; n = 109) and those without (non-COVID cohort; n = 226), and evaluated their olfaction during the postpartum period by administering the University of Pennsylvania Smell Identification Test. Participants were queried about demographics, past SARS-CoV-2 infections, self-reported sense of smell (both in overall ability to smell and for the presence of qualitative smell issues such as parosmia and phantosmia), and perceived cause of smell loss, if any. We found significantly fewer postpartum women with normosmia capabilities in both COVID (27%) and non-COVID (46%) cohorts compared to normative data for aged-matched (30 to 39 years) women (83%). Women in the non-COVID cohort had significantly higher UPSIT scores and mean subjective olfaction ratings than those in the COVID cohort (95% CI [0.77,2.41] and 95% CI [-0.83,7.34], respectively). This study reflects the largest published cohort of postpartum women evaluated for olfactory function with standardized psychophysical testing. Our findings suggest both postpartum and SARS-CoV-2 infection are associated with diminished smell function.
