Table 4. Correlation coefficients between IRT parameters and SUV_max in the hand immersion test.

	Before	After (5 min)
Tscv	-0.01	0.14
Tc	-0.12	-0.11
Δtemp	0.27	0.43*
Tscv-time	-	0.17
Tc-time	-	0.04

SUV, standardized uptake value; T_scv, skin temperature on the supraclavicular region; T_c, skin temperature on the chest region; Δtemp, differences between T_scv and T_c; T_scv-time, difference in T_scv between before and after hand immersion; T_c-time, difference in T_c between before and after hand immersion.

*P < 0.05 (Pearson’s correlation analysis).
