The NT-ProBNP Test in Subjects with End-Stage Renal Disease on Hemodialysis Presenting with Acute Dyspnea: Is Knowing Worth the Cost?

Table 3

Comparison of the high NT-ProBNP and low NT-ProBNP quartiles¹ using the Mann-Whitney U Test.

	Group	𝑁	Mean	Standard deviation	𝑃 value
Ultrafiltration (liters)	Low	59	2.11	1.18	0.14
	High	61	2.48	1.16
Weight change (kg)	Low	59	2.29	1.65	0.22
	High	61	2.70	1.66
Ejection Fraction (%)	Low	60	54.20	18.22	0.02
	High	61	50.66	15.91

¹Low group NT-ProBNP levels ≤5676 pg/mL (≤25% percentile).
High group NT-ProBNP levels ≥32499 pg/mL (≥75% percentile).
