Functional impact of long COVID among healthcare workers with comorbidities in Quebec, Canada: a cross-sectional 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: Long COVID is a frequent post-infectious chronic condition that impacts quality of life and work performance. Whether individuals with comorbidities experience a greater functional impact of long COVID is unknown. We evaluated the functional impact of long COVID among healthcare workers (HCWs) with chronic cardiovascular diseases, chronic respiratory diseases, obesity or a history of depression, and compared it with that of HCWs without comorbidities. Methods: We conducted a cross-sectional study in Quebec, Canada. We compared self-reported long COVID cases to COVID-19-infected controls without long COVID on work ability, work functioning, health-related absenteeism, dyspnoea-associated impairment and psychological distress among HCWs (a) with at least one of the four comorbidities, (b) with each of the four comorbidities and (c) without comorbidities. We used inverse probability of exposure and robust Poisson regressions to estimate adjusted prevalence differences (aPD) and prevalence ratios. Comorbidity data were obtained from the Quebec integrated chronic disease surveillance system. Results: A total of 3754 and 8439 HCWs with and without comorbidities, respectively, were included. Among HCWs with at least one of the four comorbidities, long COVID was associated with higher prevalence of low work ability (aPD=15%, 95% CI: 12% to 18%), low work functioning (aPD=27%, 95% CI: 22% to 31%), health-related long-term absenteeism (aPD=8%, 95% CI: 5% to 11%), dyspnoea-associated impairment (aPD=23%, 95% CI: 19% to 26%) and psychological distress (aPD=24%, 95% CI: 20% to 28%). aPDs were greater among HCWs with comorbidities than among those without for low work ability (p=0.013 for interaction), for low work functioning (p=0.034) and for dyspnoea-associated impairment (p<0.001). Conclusion: Long COVID is associated with significant functional impairment among HCWs with pre-existing chronic conditions. HCWs with at least one of the four comorbidities experience lower work ability, lower work functioning and more dyspnoea-associated impairment compared with those without comorbidities.
