3. Figure 2
Capillary density was significantly reduced in EM patients after central body heating in the nail bed area with the highest concentration of AV shunts. (a) EM patients and (b) healthy control group. The reduction in capillary density was significantly higher in EM patients in the nail bed area () compared to the control group (*p <0.05), in contrast to the foot arch (□).

5. Figure 3
The symptomatic subset of EM patients had more pronounced reduction in capillary density in the nail bed. (a) Symptomatic EM patients; (b) asymptomatic EM patients; and (c) healthy control group. The reduction in capillary density was significantly higher in symptomatic EM patients in the nail bed area () compared to asymptomatic patients and controls after central body heating. No such difference was found between the three groups in the foot arch, (□) but the same nonsignificant trend was observed. Distribution of data is illustrated as box plots, where the boxes show median with quartiles. *p <0.05 and **p <0.01 compared to symptomatic EM in the nail bed area.
