  1. This Bowker Test showed the distribution of subtypes of Taneichi-Score before and 3 months after radiation therapy (A). Asymmetry was apparent (p = 0.238) and the correlation (kappa = 0.55) was good. The evaluation of the distribution of subtypes A to F showed a minor change in the direction of improvement over the course of time. Deterioration occurred in 0% of the cases, improvement in 33.3% (n = 8). No change was seen in 66.7% (n = 16) of the cases. After 6 months (p = 0.629, kappa = 0.57) the distribution showed the same results of subtypes.
