Fig. 3From: Correlation between the fatty infiltration of paraspinal muscles and disc degeneration and the underlying mechanismFatty infiltration of multifidus between mild- and severe-degeneration groups. The fatty infiltration of MF in the severe-degeneration group (Pfirrmann IV) was significantly higher than that in the mild-degeneration group (Pfirrmann II). *P < 0.05Back to article page
