The graphs depict the CA at the beginning of treatment, during the serial casting period, and at the latest follow-up. The black columns depict the CA of patients with IS, and the grey columns represent the CA of patients with NIS. Likewise, statistical significance is indicated by black or grey *. With implementation of the first cast, a significant reduction in CA was achieved in both cohorts (IS p = 0.0009; NIS p < 0.0002). With the second cast, reduction in CA in relation to the CA at the beginning of treatment, was still significant (IS p < 0.0001; NIS p = 0.0036). Also, the third cast let to a reduction of significant reduction in CA, compared to the beginning of treatment (IS p = 0.0017; NIS p = 0.0019). In the follow-up controls the difference in CA was still significant to the beginning of treatment (IS p = 0.0182; NIS p = 0.0029). The error bars represent standard deviation
