Abbreviations: eGFR = estimated glomerular filtration rate, SD = standard deviation, IQR = interquartile range
Statistical significance between characteristics of residents by eGFR category detected via t-test for continuous variables, chi-square test for dichotomous variables.
a
Estimated glomerular filtration rate ≥45 ml/min/1.73m2 and <60 ml/min/1.73m2. A value less than 60ml/min/1.73m2 is considered chronic kidney disease.
b
Data was not available for all subjects. Number of subjects with missing values: Vitamin D supplement use, n=2; anemia, n=14.
