Correction to: Validity and diagnostic performance of fluorescence optical imaging measuring synovitis in hand osteoarthritis: baseline results from the Nor-Hand cohort
Arthritis Research & Therapy volume 23, Article number: 87 (2021)
Correction to: Arthritis Res Ther 22, 98 (2020)
Following publication of the original article , the authors reported an error in Fig. 2 and the other is in the supplementary Figure 1.
1. In Fig. 2 the percentage of joints with MRI-defined synovitis grade 1–3 in the thumb base is reported as 81%. The correct number is 61%. As reported under “Results, Frequency distribution of synovitis according to FOI, MRI, and ultrasound” 81% of the participants demonstrated MRI enhancement in the CMC-1 and/or STT joint. However, 61% of the total STT and CMC-1 joints examined demonstrated MRI-defined synovitis.
2. Supplementary Figure 1: Erosive and remodeling phase is reported in two identical columns. The correct figure should have only one of the two columns representing joints in erosive and remodeling phase.”
The original article has been corrected.
