94 Chapter 4 which data were adjusted for baseline costs and utility simple linear regression, is presented in the supplementary methods. The data were analyzed using IBM SPSS Statistics 24.0 (IBM Corporation, Armonk, NY, USA) and Microsoft Office Excel and Access 2013 (Microsoft Corporation, Redmond, WA, USA). Results In total, 629 patients of the DREAMeR study were randomised into control (n = 314) or intervention (n = 315) groups. Over six months, the total drop-out rate was 6.7% in the intervention group and 6.4% in the control group (p = 0.88). Costs and effects could not be obtained for 41 participants, who were excluded from the results (see Figure 1). In total, 588 patients were analysed for this study (294 in both groups). Baseline demographics of the participants in both groups are shown in Table 1. Figure 1: Study flowchart of the economic analysis of the DREAMeR study.
