Sweat output measurement of the post-ganglion sudomotor response by Q-Sweat Test: a normative database of Chinese individuals

Table 4 Linear regression “enter” analysis for the total volumes of sweat response of the four measured sites with age

Sweat volume (μl)	Forearm (Vt1)	Proximal leg (Vt2)	Distal leg (Vt3)	Foot (Vt4)
(R, R square)	(0.173, 0.030)	(0.057, 0.003)	(0.119, 0.014)	(0.203, 0.041)
Non-standardized regression equation	Vt1 = 0.640 + 0.005 × age	Vt2 = 1.007 - 0.002× age	Vt3 = 1.022 – 0.003 × age	Vt4 = 0.739 - 0.004 × age
Standardized regression equation	Vt1 = 0.173 × age	Vt2 = −0.057 × age	Vt3 = −0.119 × age	Vt4 = − 0.203 × age

Abbreviations: Vt1, square root of total volume of sweat response recorded at forearm; Vt2, square root of total volume of sweat response recorded at proximal leg; Vt3, square root of total volume of sweat response recorded at distal leg; Vt4, square root of total volume of sweat response recorded at foot.
