^a Logistic regression model, adjusted for gender, schooling and minimum wage by month. Decreased GFR defined as GFR <60 mL/min/1.73 m²

^b adjusted odds ratio.

^c Cardiovascular disease: self-reported.

^d Hypertension: self-reported or the mean of three measurements of arterial blood pressure >140/90 mmHg.

^e Diabetes mellitus: self-reported or a fasting plasma glucose ≥126 mg/dL or a glycohemoglobin ≥6.5%.
