Table 6. Mortality between 30 and 365 days postoperative assessed with stepwise logistic regression analysis.

'a' cascading to find the most significant index: Variable(s) entered on step 1: PIV^Preop, PAN^1st, PAN^3rd, SII^Preop, SII^1st, SII^3rd, NLR^Preop, NLR^1st, NLR^3rd, MLR^Preop, MLR^1st, MLR^3rd, delay to surgery. Last step 14 'a': There was no most significant index.

*PIV^Preop: Preoperative pan immune-inflammation value; PIV^1st: Pan immune-inflammation value postoperative 1st day; PIV^3rd: Pan immune-inflammation value postoperative 3rd day; SII^Preop: Preoperative systemic immune-inflammation index; SII^1st: Systemic immune-inflammation index postoperative 1st day; SII^3rd: Systemic immune-inflammation index postoperative 3rd day; NLR^Preop: Neutrophil-lymphocyte ratio preoperative; NLR^1st: Neutrophil-lymphocyte ratio postoperative 1st day; NLR^3rd: Neutrophil-lymphocyte ratio postoperative 3rd day.
