Background And Purpose

Method

Data were analysed based on Cox proportional hazards models with adjustment for relevant confounders, and the results were expressed as hazard ratios (HRs) with 95% confidence intervals (CIs). During eight years of follow-up, a total of 6024 participants died.

Conclusion

In conclusion, both severely decreased eGFR and proteinuria are independent predictors of all-cause mortality in the general northern Chinese population. A combination of severely decreased eGFR and proteinuria increases the risk of all-cause mortality, which is even over 5-fold higher in females.

Main results

The two indicators, eGFR < 45 ml/min/1.73 m2 and the presence of proteinuria, were independently associated with all-cause mortality. Compared with eGFR ≥45 ml/min/1.73 m2 with negative proteinuria, HRs of all-cause mortality were 1.26 (95% CI 1.10-1.44) for eGFR < 45 ml/min/1.73 m2 without proteinuria, 1.95 (1.78-2.14) for eGFR ≥45 ml/min/1.73 m2 with proteinuria, and 2.63 (2.14-3.23) for eGFR < 45 ml/min/1.73 m2 with proteinuria. The all-cause mortality risk of eGFR and/or proteinuria was much higher in females than in males (P for interaction < 0.01).
