Table 3.

Post hoc comparisons of relative oxyhemoglobin ([O₂Hb]) changes between painful pressure (=PAIN), nonpainful pressure (=PA30), and brushing (=Brush). A) PAIN versus PA30, B) PAIN versus Brush, and C) PA30 versus Brush. The subscript ‚ All’ means that all responders and non‐responders were included for analysis, whereas in the ‚ Responders’ group a pre‐selection took place. Results are false discovery rate (FDR) corrected (q < 0.05)
