Adjusted Incident Rate Ratio (IRR) For Death From Cardiovascular Disease During Follow-Up Interval

CharacteristicIRR95% CI
BMI=body mass index; CI=confidence interval; 25(OH)D = 25, hydroxyvitamin D; eGFR=estimated glomerular filtration rate; MET = metabolic equivalency task.
Note: IRRs are based on a fully adjusted model including all variables in table, month of baseline evaluation, and region.
