Patients were stratified according to age at surgery (<70 vs. ≥70 years). The two groups did not differ regarding baseline characteristics (). Data are given as number of events (frequency). †: statistics according to the chi-square test; /: no χ2 value was found; ∗: value for Fisher’s exact test inadequate for the chi-square test.
