Mean levels of CRP and SAA in serum as measured by ELISA

Group no.	Subject group	No. of subjects	Mean level (μg/ml)a in serum ± SE
			CRP	SAA
1	PD− CVD−	26	1.68 ± 1.42	15.92 ± 3.36
2	PD+ CVD−	20	2.40 ± 1.89	11.15 ± 4.58
3	PD− CVD+	18	3.35 ± 1.56	19.44 ± 3.70
4	PD+ CVD+	16	8.58 ± 1.74	27.75 ± 4.13

^aOverall P of <0.05 for CRP values (P = 0.0162) and SAA values (P = 0.389). Specific post hoc comparisons were as follows for CRP: P = 0.0029 (groups 1 and 4), 0.0192 (groups 2 and 4), and 0.0282 (groups 3 and 4). Specific post hoc comparisons were as follows for SAA: P = 0.0294 (groups 2 and 3) and 0.0090 (groups 2 and 4). A summary table of APP levels was determined by ELISA analysis. The data were analyzed using by ANCOVA and reported as the group mean ± SE, with an adjustment for smoking. Normal levels as reported by the kit manufacturers were as follows: CRP range, 0.6 to 1.9 μg/ml; and SAA range, 1.0 to 10.0 μg/ml (reported mean, 3.0 to 4.0 μg/ml).
