Fig. 2From: Central sensitization inventory scores correlate with pain at rest in patients with hip osteoarthritis: a retrospective studyCorrelation between the CSI score and characteristics of the hip OA patients. Correlations between the Central Sensitization Inventory score and age, duration of hip pain, visual analogue scale (VAS) pain at rest, VAS pain on activity, and Harris Hip Score in 100 patients with hip OA were evaluated using the Spearman’s correlation coefficient. Correlation coefficient is represented by r. P < 0.05 indicates statistical significance.
