---|---|---|
The mean control diameter of each vessel before HO was used for normalisation. Main effects and first order interactions are shown in the upper and middle part of the table, respectively. All components of variance and interactions were significantly larger than the residual variance (p<0.001) shown in the lower part of the table. | ||
