Table 3 Age and body mass index adjusted means (SEM) of bone mass (stiffness indexa and mBMDb) by osteophyte status at the knee, distal interphalangeal (DIP), proximal interphalangeal (PIP), carpometacarpal/metacarpophalangeal (CMC/MCP) joints.

From: Appendicular bone mass and knee and hand osteoarthritis in Japanese women: a cross-sectional study
