Figure 2. — Distribution of the Post-COVID syndrome (PCS) score in COVIDOM sub-cohorts. (a) Frequency of PCS score-defined severity classes. A PCS score of 0 (light blue, hatched) means complete absence of long-term symptoms, which was observed in 91 (15·7%, Kiel-I), 77 (27·5%, Würzburg/Berlin), and 66 (16·2%, Kiel-II) of the participants in COVIDOM, respectively. Severe PCS, defined as a PCS score ≥26·25 (dark blue), was present in 109 (18·8%, Kiel-I), 36 (12·9%, Würzburg/Berlin), and 82 (20·1%, Kiel-II) participants, respectively. (b) Cumulative distribution function of PCS score. The PCS score distribution in Würzburg/Berlin was notably different from those in the two Kiel sub-cohorts owing to a larger proportion in the former sub-cohort of participants with a PCS score equal to zero. Consequently, the mean PCS score equalled 13·0 (SD: 12·6) in Würzburg/Berlin, which was significantly lower than in both Kiel-I I (17·0, SD: 12·4) and Kiel-II (17·0, SD: 12·1; both p < 0·0001).
