Fig. 4From: Evaluation of P16 expression in canine appendicular osteosarcomaFor dogs with OSA, the disease free interval (DFI) is shorter for tumors expressing P16 relative to tumors without P16 expression. The percent survival of dogs with OSA that exhibit any P16 staining (+1, +2 or +3, dashed line) and dogs with OSA that lack P16 staining (solid line) are plotted in this survival plotBack to article page
