Table 2.
Hazard ratios for the association between changes in proteinuria and all-cause mortality from 2006–2008.
| Changes in proteinuria | P trend | Per degree decrease | |||
|---|---|---|---|---|---|
| Elevated proteinuria | Stable proteinuria | Reduced proteinuria | |||
| All participants | |||||
| Model 1 | 1.92 (1.66–2.23) | 1 | 0.75 (0.60–0.95) | <0.0001 | 0.71 (0.67–0.75) |
| Model 2 | 1.67 (1.44–1.94) | 1 | 0.71 (0.56–0.90) | <0.0001 | 0.75 (0.71–0.79) |

Model 1: adjusted for the levels of baseline proteinuria; model 2: adjusted for age, gender, and baseline proteinuria; model 3: adjusted for age, gender, level of education, income, smoking, alcohol abuse, amount of physical activity, body mass index, and baseline proteinuria; model 4: adjusted for variables in model 3 plus history of hypertension, diabetes, dyslipidemia, total cholesterol, triglycerides, low-density lipoprotein, high-density lipoprotein, fasting plasma glucose, and creatinine. ∗The P value of interaction between proteinuria changes and diabetes status for all-cause mortality is 0.4274.
