Thanks for your kindly reply! However, not sure how to apply the risk equation: risk_score = 0.0634*age + 0.0897 *m_b_hbA1C + 0.5314*log10( m_U_ACR) 5_year_probability = 1-0.9707**(Risk_Score-4.5674) into my dataset to look into the c-statistics and ROC curve for this equation? Looking forward your kindly reply
