Resistance exercise improves physical fatigue in women with fibromyalgia: a randomized controlled trial

Table 2 Spearman’s correlation coefficients (r _s) with p values for correlation between change (posttest-baseline) in the five subscales of the Multidimensional Fatigue Inventory-20 and patient characteristics, symptoms and physical function (n = 105)
