Correction: Reduced activity, reactivity and functionality of the sympathetic nervous system in fibromyalgia: An electrodermal study

In Table 1, the values in the last three rows of column “p” are mistakenly duplicated in column “η2.” Please see the correct Table 1 here.

Table 1. Demographic, clinical, medication use (number of participants and percentage in brackets) and physiological data in fibromyalgia (FMS) patients and healthy participants.
