Table 2 Association of adiponectin and radiographic severity of osteoarthritis

From: Adiponectin associates with markers of cartilage degradation in osteoarthritis and induces production of proinflammatory and catabolic factors through mitogen-activated protein kinase pathways

  Ahlbäck grades 4 and 5 Ahlbäck grades 1 to 3
Patient characteristics Crude OR 95% CI P-values Adjusted OR 95% CI P-values
Plasma adiponectin (μg/ml) 2.2 1.1 to 4.3 0.022 2.2a 1.1 to 4.4 0.022
     1.9b 0.9 to 3.8 0.090
Culture media adiponectin (pg/mg cartilage) 1.1 1.0 to 1.2 0.007 1.1a 1.0 to 1.2 0.007
     1.1b 1.0 to 1.2 0.016
