| Group | PRP1 | HC (N = 30) | FMS (N = 90) | Total | |||
| N | % | N | % | N | % | ||
| 1 | Low BP | 6 | 20.0 | 42 | 46.7 | 48 | 40.0 |
| 2 | High BP | 5 | 16.7 | 34 | 37.8 | 39 | 32.5 |

Bold text indicates the highest values of each group. 1Psychophysiological response patterns: Low BP: low systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), skin conductance level (SCL) and electromyographic activity (EMG); High BP: enhanced SBP, DBP, HR as well as moderate SCL and low EMG; High EMG: enhanced EMG as well as stable physiological response; High SCL: enhanced SCL as well as enhanced BP, moderate HR and reduced EMG. HC, healthy control; FMS, fibromyalgia syndrome.
