  1. Continuous variables are expressed as mean ± standard deviation. Nominal variables are expressed as number (%). Differences between two of the four groups were analyzed using Tukey’s test for multiple comparisons. # Of the two preliminary parameters, FTC showed the same tendency as that of RVEF.
