1 Subregional laminar cartilage MR spin–spin relaxation times (T2) in osteoarthritic knees with and without medial femorotibial cartilage loss – data from the Osteoarthritis Initiative (OAI)  W. Wirth, S. Maschek, P. Beringer, F. Eckstein  Osteoarthritis and Cartilage  Volume 25, Issue 8, Pages (August 2017) DOI: /j.joca Copyright © 2017 Osteoarthritis Research Society International Terms and Conditions

2 Fig. 1 Flowchart illustrating the process of selecting case knees with structural progression exceeding the smallest detectable change (SDC) threshold for both minimum radiographic joint width (mJSW) and cartilage thickness (ThC) in the medial femorotibial compartment (MFTC) between the baseline (BL) and the year-one (Y1) follow-up visit and control knees without progression in minimum JSW (mJSW), MFTC or lateral femorotibial compartment (LFTC) cartilage thickness. The case and control knees were matched by sex, BMI, baseline Kellgren–Lawrence grade (KLG 2/3), and pain.
