Results of Kolmogorov–Smirnov Test for Each Method
| Parameter | Method A vs. B, D(n) D(n,α) | Method A vs. C, D(n) D(n,α) | Method B vs. C, D(n) D(n,α) |
| LVEF, Kolmogorov–Smirnov test | 0.05 < 0.24 | 0.09 < 0.24 | 0.10 < 0.24 |
| EDV, Kolmogorov–Smirnov test | 0.06 < 0.24 | — | — |
| ESV, Kolmogorov–Smirnov test | 0.08 < 0.24 | — | — |
If data are normally distributed, then critical value D(n,α) will be larger than D(n). D(n,α) is found in Kolmogorov–Smirnov table, for n = 28 and α = 0.05 D(n,α) = 0.24. D(n) is calculated for each method comparison and is in all cases lower than D(n,α). All data are normally distributed.
