Remnant Gastric Cancer Risk Calculator

Score Calculation Rules:
- Prognostic Nutritional Index = 10 × Albumin (g/dL) + 0.005 × Lymphocyte count (/mm³)
- NLR = Neutrophil count / Lymphocyte count
- CONUT: Based on serum albumin, cholesterol, and lymphocyte count

Logistic regression model used:
Risk = 1 / (1 + exp(-(a + b × TotalScore)))
a = -5.2, b = 0.08
