*Values are median (interquartile range) and percentage of the total population with abnormal results according to cut off values shown in Table S1 in the Online Supplementary Document. Scales and instruments used to measure each symptom or test are shown in Table S1 in the Online Supplementary Document. Dyspnoea was missing for 8 participants; SpO2 at rest was missing for 3 participants; sit-to-stand test was missing for 73 participants; forced vital capacity was missing for 108 participants; x-ray was missing for 122 participants; HADS was missing for 78 participants; posttraumatic stress disorder scale was missing for 14 participants; post COVID functionality was missing for 3 participants; insomnia was missing for 3 participants; fatigue was missing for 3 participants; muscle/joint pain was missing for 15 participants; loss of smell was missing for 22 participants; loss of taste was missing for 34; muscle strength was missing for 23; quality of life was missing for 4.
