Chronic Kidney Disease Stage Is a Modulator on the Association between High-Sensitivity C-Reactive Protein and Coronary Vasospastic Angina

Table 2

The laboratory data about peripheral monocyte blood cell count and hs-CRP according to CKD stage.

	CKD stage 1	CKD stage 2	CKD stage 3	P value^#
	𝑁=245	𝑁=518	𝑁=156
Peripheral monocyte blood cell count, /mm^3	336±260	356±349	397±271	0.314
hs-CRP, mg/L	4.30±5.98	4.19±5.36	8.15±14.53^†‡	<0.001

Data are presented as mean ± standard deviation.
^#Statistical significance based on one-way ANOVA analysis for continuous variables.
^†𝑃<0.05 between CKD stage 1 patients and CKD stage 3 patients.
^‡𝑃<0.05 between CKD stage 2 patients and CKD stage 3 patients.
Statistical significance of peripheral monocyte blood cell count based on 𝑡-test for continuous variables.
Statistical significance of hs-CRP based on Mann Whitney test for continuous variables due to hs-CRP levels was not normally distributed.
CKD: chronic kidney disease; hs-CRP: high-sensitive C-reactive protein.
