Table 4. Odds ratios of current smoking for high plaque burden and for presence of high risk lesion types.

	OR (95% CI)	P-value
(VH-)IVUS segment parameters
Plaque burden
Below the median	1.00 (reference)
Above the median	1.69 (1.04–2.75)	0.033
(VH-)IVUS lesion parameters
≥1 Lesion with plaque burden ≥70%	1.20 (0.66–2.17)	0.55
≥1 Lesion with MLA ≤4.0mm2	1.03 (0.63–1.71)	0.90
≥1 TCFA	1.00 (0.63–1.60)	1.00

OR, odds ratio; CI, confidence interval; MLA, minimal lumen area; TCFA, thin-cap fibroatheroma.

P-values were obtained by conditional logistic regression.
