Percentage of participants with decreased glomerular filtration rate (GFR) by occupational grade and sex. P value for trend calculated using a regression model adjusted for age. Decreased GFR defined as GFR estimate <60 mL/min/1.73 m2 using the isotope-dilution mass spectrometry–traceable CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) equation. Total percentage of cases was 7.8% in men and 11.0% in women.
