MVD, MVA, and MVC of NM, HP, and TA. MVD and MVA differed significantly between NM and TA and between HP and TA, but did not differ significantly between NM and HP in the upper layer. MVC differed significantly between NM and HP and between TA and HP in the upper layer. There were no significant differences in MVD, MVA, or MVC between NM, HP, or TA in the middle layer or lower layer. When microvessel analysis was done after combining the upper and middle layers (0–300 μm) or the upper, middle, and lower layers (0–450 μm), MVD differed significantly between HP and TA in the upper layer, but there were no significant differences in upper and middle layer (0–300 μm) or all layers (0–450 μm)
