*means that P<0.05, with statistical significance. Mean (N)WC/IC was the average of the six measurements mentioned in the method. Random (N)WC/IC was the random of the six measurements mentioned in the method. Most of the Mean and Random (N)WC/ICs showed moderate correlation with MVD, MVA and microvascular grading
