Fig. 1From: Simplified Chinese version of hip and knee replacement expectations surveys in patients with osteoarthritis and ankylosing spondylitis: cross-cultural adaptation, validation and reliabilityBland–Altman plots of test–retest reliability of the SC-THRES/TKRES. The plots are for the (a) hip OA group, (b) AS group and (c) knee OA group. Each data point indicates how the difference between the two test sessions for an individual patient compares to the mean of the two sessions for scores of the SC-THRES/TKRES. The long dashed line shows the 95% (±1.96 SD) limits of agreement.
