Integer scores were assigned to variables based on the magnitude of associations: 2 for age 50\u201359\u2003years, 3 for age 60\u201369\u2003years and 4 for age 70\u2003years or older, and 1 for female gender, anaemia, hypertension, diabetes, proteinuria and cardiovascular disease. Based on the Youden index, a value of 4 or greater defined a high risk population with sensitivity 89%, specificity 71%, and positive predictive value 19%, and negative predictive value 99%.
