Associations of serum alkaline phosphatase levels as a categorical variable^a with elevated serum CRP levels (> 3 mg/l) in CKD population in logistic regression models without and with adjustment for serum vitamin D levels

	Model 1^b		Model 2^c

Serum alkaline phosphatase group	Odds	95% CI	Odds	95% CI
≤ 75 IU/l	1.00		1.00
76–90 IU/l	1.24	0.71–2.16	1.24	0.71–2.18
91–111 IU/l	1.93	1.26–2.94	1.97	1.28–3.01
≥ 112 IU/l	2.52	1.44–4.43	2.59	1.47–4.57

Abbreviations: CI, confidence interval; CKD, chronic kidney disease; CRP, C-reactive protein.

Serum alkaline phosphatase groups defined by serum alkaline phosphatase quartiles in the CKD participants.

Model 1. Adjusted for age, gender, race, myocardial infarction, stroke, congestive heart failure, diabetes, hypertension, waist circumference, physical inactivity, smoking, estimated glomerular filtration rate, hemoglobin, serum calcium, phosphorus, aspartate transaminase, alanine transaminase, bilirubin, and fasting glucose.

Model 2. Adjusted for Model 1 variables and serum 25-hydroxy vitamin D level.
