This Bowker test shows the distribution of subtypes of Taneichi score prior to RT and at the first follow-up examination after RT. The evaluation of the distribution of subtypes A to G shows in 16% of the study patients (n = 33) an improvement of stability over the course of time. Deterioration of stability occurs only in 3% of the patients (n = 6), while in the majority of patients who were still alive at the first follow-up examination (81%, n = 169) no change of the stability is evident
