A logistic regression model was built to predict elevated SUA, and its performance was validated.Results: The risk prediction model showed good discrimination ability in both the development cohort (area under the curve (AUC) = 0.82; 95% confidence interval (CI) =0.79~0.86) and the external validation cohort (AUC=0.76; 95% CI=0.70~0.82). The model was adequately calibrated, and the predictions correlated with the observed outcome (χ2 = 6.36, P = 0.607). Men were more prone to elevated SUA levels than women were, and a baseline SUA level ≥ 360 μmol/L was a common risk factor for both males and females. Proteinuria status was an additional risk factor for males, whereas a baseline estimated glomerular filtration rate (eGFR)< 60 mL/min· 1.73 m2 and diabetes status were additional risk factors for females.Conclusion: The externally validated nomogram, which is predictive of elevated SUA in older adults, might aid in the detection of individual diseases, the development of preventive interventions and clinical decision-making.Keywords: elevated serum uric acid, prediction nomogram, risk factor |
