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