Data are reported as median [Q1 to Q3], where Q is the quartile (a) or no. (%) (b) according to the type of raw data. Stat. = statistics of the test; p-value = probability associated with the statistics of the test. Mann–Whitney test was used to compare two independent groups for quantitative data (a). Chi-squared or Fisher’s exact test was used to compare qualitative data (n.a. = not applicable to the Fisher’s exact test) (b). ICU = intensive care unit; T = tumor invasion; N = lymph node invasion; M = presence of metastases.
