Figure 2.

The distribution of endothelial function in 74 subjects considered to have normal health status in health check-ups. The open dots indicate RH-PAT index values of ≥1.67 and black dots indicate RH-PAT index values of <1.67. An index value of <1.67 was considered to indicate endothelial dysfunction (low response). Overall, 33.8% (25/74) of the healthy subjects had endothelial dysfunction. There were no significant differences nor correlation in RH-PAT index values between sexes A or age groups B.

Abbreviations: ns, not significant; RH-PAT, reactive hyperemia peripheral arterial tonometry.
