Data are reported as number of patients (%) or mean (± standard deviation), as appropriate. p-Values are based on Student’s t-test, χ2 test or Fisher’s exact test, as appropriate. Note that for some characteristics frequencies over categories do not sum to the total number of patients, because there were some missing values.
