Total CKD risk score = sum of points for each predictor at baseline (before or early in antiretroviral therapy):

Predictor	Definition	Points
Age	19–39 years	0
	40–49 years	2
	50–59 years	4
	60–90 years	6
Glucose	Glucose >7.8 mmol/L (>140 mg/dL)	2
Systolic blood pressure	Systolic BP >140 mmHg	1
Hypertension	Clinical diagnosis of hypertension	2
Triglycerides	Triglycerides >2.3 mmol/L (>200 mg/dL)	1
Proteinuria	Proteinuria present on urinalysis or quantitative testing	2
CD4⁺ count	CD4⁺ <200 cells/µL	1

Total score = 0 to ≥15 points. Higher scores indicate higher 5-year risk of CKD. The original model used this point score within a Cox model to estimate 5-year CKD risk separately for regimens with and without tenofovir disoproxil fumarate (TDF). This implementation returns the point score and risk band. 5-year percentages are described in the Evidence & Context section.
