| Variables | Model 1 | Model 2 | SBS | ||
|---|---|---|---|---|---|
| β | HR (95% CI) | β | HR (95% CI) | P | |
| Age (years) | 0.025 | 1.02 (1.01–1.03) | – | – | – |
| Age range (0, <55 years; 1, ≥55 years) | – | – | 0.569 | 1.77 (1.31–2.38) | 2 |
| BMI (kg/m2) | 0.132 | 1.14 (1.1–1.18) | – | ||
| Obesity (0, BMI <25; 1, ≥25 kg/m2) | – | – | 0.568 | 1.76 (1.4–2.22) | 2 |
| TG (mmol/L) | 0.154 | 1.17 (1.09–1.25) | – | – | – |
| Hypertriglyceridemia (0, no; 1, yes) | – | – | 0.442 | 1.56 (1.25–1.94) | 2 |

Model 1 score (continuous variable) = 0.025 × age + 0.154 × TG + 0.132 × BMI + 0.974 × FPG. Model 2 score (binary variable) = 0.569 × age (0, age <55 years; 1, age ≥55 years) + 0.442 × TG (0, no;1, yes) + 0.568 × obesity (0, BMI <25;1, BMI ≥25 kg/m2) + 0.773 × non‐alcoholic fatty liver disease (0, no; 1, yes) + 1.148 × IFG (0, no; 1, yes). Model 3 Score (SBS) = age(0, age <55 years; 1, age ≥55 years) × 2 + TG (0, no; 1, yes) × 2 + obesity (0, BMI <25; 1, BMI ≥25 kg/m2) × 2 + non‐alcoholic fatty liver disease (0, no; 1, yes) × 2 + IFG (0, no; 1, yes) × 3. BMI, body mass index; FPG, fasting plasma glucose; HR, hazard ratio; IFG, impaired fasting glucose; NAFLD, non‐alcoholic fatty liver disease; P, points scored; SBS, Shanghai Baosteel Score; TG, triglycerides.
