High red blood cell distribution width is closely associated with in-stent restenosis in patients with unstable angina pectoris

Table 2 Comparison between the baseline RDW and the follow-up RDW

	RDW_baseline (Mean ± SD)	RDW_followup (Mean ± SD)	RDW change (Mean ± SD)	P value
Overall (%)	13.1 ± 0.8	13.4 ± 1.0	0.2 ± 0.8	<0.001
Non-ISR (%)	13.0 ± 0.8	13.2 ± 0.8	0.2 ± 0.8^a	0.003
ISR (%)	13.7 ± 0.8	14.0 ± 1.4	0.3 ± 0.9^a	0.022

^aThe difference of RDW changes between in Non-ISR and ISR groups is not statistically significant (P = 0.472)
ISR In-stent restenosis, RDW Red blood cell distribution width, SD Standard deviation
