Figure 3.

Comparison between the maximum ear thickness (A), the maximum erythema score (B) or the maximum desquamation score (C), and dose of irradiated ears after a 4-fraction course given one fraction per day. The days and the values on which the maximum erythema score, desquamation score and ear thickness were assessed are shown in Table 1 and Table 2. Correlations were calculated using Spearman’s correlation with linear regression. Significance levels are indicated. The errors are given as the standard errors of the mean (SEM).
