Effects of Cervical Rotatory Manipulation (CRM) on Carotid Atherosclerosis Plaque in Vulnerability: A Histological and Immunohistochemical Study Using Animal Model

Table 4

Histological characteristics of carotid plaques in the CAS-CRM group and the CAS group (mean±SD).

Group	N	Ratio of collagen fiber (%)	MVD (N/mm^2)	Mean IOD(10^−3)
CAS-CRM	8	35.31±18.02	23.43±6.74	2.85±1.23
CAS	10	55.36±19.36	12.97±10.39	0.62±0.48
P		0.039	0.026	0.001

CAS, carotid atherosclerosis; CRM, cervical rotatory manipulation; MVD, mean micro-vessel densities; Mean IOD, mean integrated optical densities.
