Table 1 Sensitivity analysis of cross-sectoral inter-rater reliability using multilevel regression modelling (with CFS-DK scores as outcome). Presented are linear regression coefficients (‘estimates’) with 95% confidence intervals (CI) for ratings according to professional group and length of clinical experience compared to the cross-sectoral regression coefficient. The random effects terms for raters and cases are also presented
