A one-sided test of non-inferiority of Traumeel® S with respect to dexamethasone at level 0.025 was computed using an analysis of covariance (ANCOVA) model with treatment group as qualitative factor and the baseline value of the abduction rotation pain VAS for active external rotation as a covariate. The test decision was based on a one-sided 97.5% confidence interval for the corresponding treatment difference. The non-inferiority margin was set to 13 mm on a 0 - 100 mm VAS scale.
