Figure 4 Relation Between Collagen Content and PSOCT Birefringence, {Phi}

(A) High positive correlation is demonstrated between {Phi} and total collagen content in all plaques (r = 0.67, p < 0.0001). (B) High positive correlation is demonstrated between {Phi} and total collagen content in fibrous caps of NCFAs (r = 0.68, p < 0.001). (C) Strong positive correlation is demonstrated between {Phi} and thick collagen fiber content (r = 0.76, p < 0.0001). (D) An inverse relationship is demonstrated between {Phi} and thin collagen fiber content (r = –0.48, p < 0.0001). The dotted lines show 95% prediction intervals. Abbreviations as in Figures 1 and 3.
