Table 4 New scoring system

From: Effective prediction of postoperative complications for patients after open hepatectomy: a simplified scoring system based on perioperative parameters

Variables Conditions Scores
Diabetes No 0
Yes 1
Scale of surgery < 6 0
≥6 1
Serum potassium ≥3.835 0
< 3.835 1
Blood loss versus body weight < 7.846 0
≥7.846 1
  1. Note: Score 0 would be calculated if no diabetes, scale of surgery (< 6), serum potassium (> 3.835), or blood loss versus body weight (< 7.846). When diabetes (yes), scale of surgery (≥6), serum potassium (≤3.835), Blood loss versus body weight (≥7.846) was fulfilled, each parameter would be scored with 1 point. The total score (TS) was calculated as the sum of the four variables
