  1. Fold change and median threshold cycle for all metalloprotease genes showing significant difference at P < 0.01 between osteoarthritis (OA) versus fracture to the neck of femur (NOF). P value from the Mann-Whitney U test. ADAM, a disintegrin and metalloproteinase domain; ADAMTS, a disintegrin and metalloproteinase domain with thrombospondin motifs; MMP, matrix metalloproteinase.
