Table 3.

Median and range of the fraction number where the exponentially weighted moving average (EWMA) statistic exceeded a 2 mm clinical limit before the end of treatment week 4, and the proportion of cases where the existence of a trend was confirmed by the accuracy interval of the trend exceeding the clinical limit before the end of treatment. This proportion is also expressed as percentage representing the robustness of the trend detection with the corresponding 95% confidence interval. EWMA parameters were established from deformable image registration (DIR) raw data. (BOS = base of skull; Occ = occipital; Max = maxilla; Mand = mandible).
