Morphometric analyses. Methods used for morphometric analyses as described in text. Area enclosed by the solid black line is the luminal area, area enclosed by the blue line is the combined luminal plus neointimal area and the area enclosed by the red is the luminal + intima–media area. Double-headed black arrows show intimal thickness (lt) and maximal intimal thickness (Max It) The white double-headed arrows represent medial thickening measurements for average and maximal intimal to medial thickness (Mt) ratios.
