Overall and recurrence-free survival with respect to changes in skeletal muscle index (SMI) or serum carbohydrate antigen 19–9 (CA 19–9) levels in the early postoperative period. a Overall survival of patients in whom SMI decreased or increased postoperatively (42 months [95% confidence interval (95% CI), 31–64] vs. not reached (NR) [95% CI, 53-NR], P = 0.002). b Recurrence-free survival of patients in whom SMI decreased or increased postoperatively (20 months [95% CI, 16–31] vs. NR [95% CI, 55-NR], P = 0.001). c Overall survival of patients with serum CA 19–9 > 37 or ≤ 37 U/mL (32 months [95% CI, 24-NR] vs. 64 months [95% CI, 42-NR], P = 0.136). d Recurrence-free survival of patients with serum CA 19–9 > 37 or ≤ 37 U/mL (15 months [95% CI, 5-NR] vs. 31 months [95% CI, 24–60], P = 0.176)
