Compared to Pavia, the participants from Lumezzane were more likely to be female, obese, and suffer from congestive heart failure, with a longer LoS in acute hospitals and in study centres and a longer time from admission to acute care hospitals, with a higher Barthel index, CRP, albumin, PaCO2, baseline Borg-D, and baseline Borg-F as well as lower D-dimer and ferritin and a lower walked distance at 6MWT and baseline SpO2. Here, ALB is linked to congestive heart failure.
