- This table shows all experimental conditions and the number of subjects in our experiment. The Mix-more-DRG (FFS) means higher DRG (FFS) weight in mixed payment schemes. A-D2, A-D4, A-D6 are the pure DRG, adjusted Mix-more-DRG(2), Mix-more-DRG(4), Mix-more-DRG(6). A-F8 and A-F6 are the pure FFS, adjusted Mix-more-FFS(8) and Mix-more-FFS(6). P-N-D2: the presentation of pure DRG (DRGpre) and non-adjusted Mix-more-DRG(2) (NA-mix-more-DRG(2)). P-N-F8: the presentation of pure FFS (FFSpre) and non-adjusted Mix-more-FFS(8) (NA-mix-more-FFS(8)). The group VI and group VII were designed to test whether the difference in presentation of the payment schemes (pure payment schemes or mixed payment schemes) affected physicians’ behavior. The results on the “presentation effects” in group VI and group VII were reported in the “Additional file 4”
