Notes: for the temperature parameters, the median value during 10 min sitting and 8 min walking in the laboratory, respectively, was used for the analyses. P-values are one-tailed. Bold values indicate statistical significance. Due to the use of preplanned hypotheses and the exploratory nature of this study, p-values were not adjusted for possible multiple comparison effects (Perneger, 1998; Streiner and Norman, 2011; Armstrong, 2014; Ranstam, 2016). FNAME-12, Face-Name Associative Memory Exam; QMCI, Quick Mild Cognitive Impairment screen; TMT-A, Trail Making Test part A; TMT-B, Trail Making Test part B; Ts_rib, skin temperature at rib cage; Ts_scapula, skin temperature at scapula; *p < 0.05, statistically significant.
