106 FIGURE 1. Flowchart of participating patients and physiotherapists There was a wide variety (3-100%) in the percentage of missing data on the dependent variable between physiotherapists. This was not correlated to the mean difference in severity of shoulder complaints (r = -0.061). 10 physiotherapists did not register severity of the complaint for any patient resulting in 1,013 patients and 46 therapists eligible for further analysis. In table 1 the characteristics of participating physiotherapists are presented. TABLE 1.
