Decreased Regulatory T Cells in Vulnerable Atherosclerotic Lesions: Imbalance between Pro- and Anti-Inflammatory Cells in Atherosclerosis

Table 2

Histological criteria for the determination of atherosclerotic plaques as “stable” or “unstable.”

	Stable plaque (SP)		Unstable plaque (UP)		value
	Median	25–75% CI	Median	25–75% CI
Fibrous cap (in μm)	267	181–440	96	0–223	0.02
LCR	0.21	0.08–0.28	0.64	0.54–0.76	<0.001
Neovessels (/0.2 mm^2)	0	0–0.3	3	3–5	<0.001

LCR: lipid core ratio; LCR: lipid core area/plaque area × 100.
