Table 3 Individual and pooled correlations between pain intensity and other self-reported variables

From: Safety and feasibility of a home-based six week resistance training program in juvenile idiopathic arthritis

  R range No. of participants with a significant correlation (P < 0.05) R pooled (across all data points from all participants) Significance of R pooled
End-of-day PI and stiffness .221 to .911 5 of 6 .864 p < 0.001
End-of-day PI and fatigue .120 to .833 2 of 6 .581 p < 0.001
End-of-day PI and mood -.836 to .244 3 of 6 -.637 p < 0.001
PI before-exercise and PI after-exercise .748 to .980 5 of 6 .912 p < 0.001
PI before-exercise and RPE -.524 to .785 1 of 6 .327 p < 0.001
PI after-exercise and RPE -.410 to .867 1 of 6 .324 p < 0.01
  1. Note: Only 6 out of 7 participants contributed data for the correlation analyses.
  2. Abbreviations: PI pain intensity, RPE ratings of perceived exertion.
