Temporomandibular Joint Bone Tissue Resorption in Patients with Early Rheumatoid Arthritis Can Be Predicted by Joint Crepitus and Plasma Glutamate Level

Figure 1

Scatter plots showing (a) the relationship between plasma level of glutamate and temporomandibular joint (TMJ) bone erosion score in the patients with crepitus ($r_s=-0.35\text{,}$$n=12\text{,}$$P=.253$) and (b) in the patients with no crepitus ($r_s=0.45\text{,}$$n=35\text{,}$$P=.007$). $\bullet$: crepitus, $\circ$: no crepitus.
