Lack of association of CRT with inflammatory markers in 118 patients

	n < limit	β (X4 vs R5)	Lower limit	Upper limit	p value
			CI 95%	CI 95%
hsPCR (log)	62	0.501	−1.219	2.22	0.57
D-dimers (log)	0	0.280	−1.336	0.777	0.60
IL-6 levels (log)	23	0.022	−0.175	0.131	0.78
IL-7 levels (log)	89	0.259	−1.184	0.666	0.58

N: number of patients; limit: detection limit of the assay; β: coefficient of interval regression; CI: confidence interval.

Since inflammation marker measurements are subject to lower detection limits, the association of IL-6, IL-7, HsPCR, D-dimers and CRT was analyzed with interval regression by means of the intreg command Stata after log transformation (natural logarithm). None of the markers resulted significantly associated with CRT.
