Corrigendum to "Synovial volume vs synovial measurements from dynamic contrast enhanced MRI as measures of response in osteoarthritis" [Osteoarthritis Cartilage 24 (2016) 1392-1398].

We have been notified by the authors that there was an error in the second sentence of the paragraph headed ‘Image analysis: segmentation’ on p. 1394 of the above article. The term interobserver should have been intraobserver. The correct sentence is as follows: Manual segmentation of the synovial tissue layer was performed on these sagittal post-contrast knee images by a single observer (intraobserver ICC = 0.94), who assessed baseline and follow-up visit MR images paired, but blinded to order. The authors would like to apologise for any inconvenience caused.
