Fig. 3From: Nitric oxide-associated chondrocyte apoptosis in trauma patients after high-energy lower extremity intra-articular fracturesTiming of chondrocyte apoptosis. The rate of chondrocyte apoptosis has a moderate correlation of 0.62 with a coefficient of demonstration (r 2) of 0.38 (p = 0.01) indicating that 38 % of the decreasing rate of chondrocyte apoptosis is the result of increasing time from injuryBack to article page
