mWAI: Work ability index modified; P15: 15th percentile; for the model we only included the most prevalent seven clusters of symptoms (not present before the acute SARS-Cov-2 infection), irrespective of WAI<P15; bold letters indicate statistical significance at P <0.05
a: adjusted for sex, age, education, marital status, nationality, smoking, obesity, work demands, medical treatment during acute infection, and the post-COVID symptom clusters indicated in the table; a prevalence difference of 0 indicates the comparison group.
