The six-month and first-year patient survival rates were similar between the <20 years, 20–40 years, 40–60 years, and ≥60 years groups, showing only a slightly significant difference (Log-rank p = .0314 and p = .0372); however, the five-year and during the study period patient survival rates in these groups were significantly different (Log-rank p < .001 and p < .0001).
