Comparisons of serum magnesium concentration between PPI group and control group

	Control group	PPI group	P^⁎	P^†
Baseline (mg/dL)	2.03±0.18	2.03±0.18	0.948
Follow-up (mg/dL)	2.07±0.21	2.05±0.20	0.190
Change (mg/dL)	0.04±0.23	0.02±0.23	0.269	0.103

Values are N, mean ± SD.

ANCOVA, analysis of covariance; Ca, calcium; GFR, glomerular filtration rate; K, potassium; PPI, proton pump inhibitor.

^⁎

P value by Student t test.

^†

P value by ANCOVA adjusting for age, sex, baseline GFR, baseline Ca, use of diuretics, and baseline K.
