This Bowker Test showed the distribution of subtypes of Taneichi-Score before and 6 month after radiation therapy. Asymmetry was apparent (p < 0.001) and the correlation (kappa = 0.614) was good. The evaluation of the distribution of subtypes A to F showed a major change in the direction of improvement over the course of time. Deterioration occurred in no cases, improvement in 44% (n = 15). No change was seen in 56% (n = 19) of the cases.
