Adjusted Effect Measures for the Association of Participant Characteristics with Year One Blood Creatinine Concentration Using Multiple Linear Regression (N = 1,500).

Of N = 1,627 participants with year one creatinine available for analysis, 127 are not included due to missing data (see Table 1). CI, confidence interval.
Characteristics chosen for inclusion by backward elimination using the Akaike Information criterion for model selection, with race, Hispanic ethnicity and randomized vitamin D treatment group forced into the model; characteristics are from baseline, except diuretic use (see 2); results for study centers not shown.
1Characteristics are modeled as continuous variables with units as shown.
2Diuretic use between baseline and year one blood draws.
3Change in creatinine (mg/dL) associated with the exposure (mean, coefficient).
