Subgroup Analyses of the Multivariate Linear Regression Analysis (Model 3) With PTH for Nocturnal Systolic and Diastolic Blood Pressure in 273 Hypertensive Patients

	Selection Criterion	Median PTH, pg/mL	Systolic Nocturnal Blood Pressure		Diastolic Nocturnal Blood Pressure
	Selection Criterion	Median PTH, pg/mL	Adjusted β‐Coefficient	P Value	Adjusted β‐Coefficient	P Value
NT‐proBNP, pg/mL	>85	49 (38–58)	0.179	.03	0.313	<.01
NT‐proBNP, pg/mL	<85	51 (40–51)	0.078	.4	0.002	.99
PAC, ng/dL	>15.5	52 (41–62)^a	0.149	.10	0.198	.03
PAC, ng/dL	<15.5	49 (37–61)^a	0.178	.06	0.166	.08
eGFR, mL/min/m²	≥60 (n=234)	49 (39–59)	0.154	.02	0.151	.02

The multivariate linear regression analysis (model 3) was repeated in subgroups. Stratified analyses were based on median N‐terminal pro‐brain natriuretic peptide (NT‐proBNP) and plasma aldosterone concentration (PAC). Mann‐Whitney U test was used to calculate differences of parathyroid hormone (PTH) between subgroups. ^a P<.5.
