Association of best independent variables with SBP at crises using linear model analysis (adjusted for covariates) (N = 293).

	SBP at Crises
Independent Variables	β ± SE	p-Value
Serum Magnesium (per 1 mg/dL increase)	11.25 ± 4.67	0.017
Serum Calcium (per 1 mg/dL increase)	9.50 ± 3.37	0.006
Corrected Calcium (per 1 mg/dL increase) (N = 207)	−7.82 ± 3.54	0.029
Use of Home Proton Pump Inhibitors	9.13 ± 3.85	0.019

Covariates in the mixed model—age, sex, race, history of diabetes, BMI, use of proton pump inhibitors at home, use of blood pressure medications at home or hospital, use of oral magnesium at home, use of intravenous magnesium at hospital, serum magnesium at crises, serum calcium at crises, corrected calcium at crises, and serum potassium at crises. p-values < 0.05 defined as significant for best independent variables.
