  1. *most significant parameter.
  2. † When an α/β ratio of 2 or 4 was used, different parameters were statistically significant in multivariate analysis (Group A: VBED30 for α/β ratio = 2 and VBED25 for α/β ratio = 4, Group B: VBED25 for α/β ratio = 2 and VBED20 for α/β ratio = 4). Therefore, we compared same parameters in each group using an α/β ratio of 2 or 4 (VBED25 and VBED30 for α/β ratio = 2 and VBED20 and VBED25 for α/β ratio = 4).
  3. Abbreviation: AUC = area under the curve.
