Postoperative morbidity adversely impacts oncological prognosis after curative resection for hilar cholangiocarcinoma

Figure 3 Overall survival and recurrence-free survival curve comparisons among patients without postoperative morbidity, with minor postoperative morbidity, and with major postoperative morbidity. A: Overall survival, P = 0.231 (with minor postoperative morbidity vs without postoperative morbidity), P < 0.001 (with major postoperative morbidity vs without postoperative morbidity); B: Recurrence-free survival, P = 0.132 (with minor postoperative morbidity vs without postoperative morbidity), P < 0.001 (with major postoperative morbidity vs without postoperative morbidity).
