Figure 4. Correlation of SA score with radiation dose and the time trend of trismus development.

Figure 4

(a) Correlation of the received radiation dose of individual masticator structures with their two year SA scores summation (r = 0.48, p<0.0001). (b) Evolution of the SA scores and the trismus grade over time. Gradual decrease of trismus severity grade (▾) and SA scores (□) is noted within 24 months.
