aRural is defined as residing in a location with a population of ≤10,000 individuals.

bComorbidities in the 5 years prior to index date were considered.

cLaboratory measurements in the year prior to index date were considered, using the most recent value. eGFR was determined using the CKD-EPI equation.

dMissing values, n = 7,986 (32%)

ePrescriptions dispensed in the 120 days prior to index date were considered.
