  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
