Table 1. The mean of VAF of each number of modules.
| Number of modules | 1 | 2 | 3 | 4 | 5 | 6 | 7 | |
|---|---|---|---|---|---|---|---|---|
| VAF (%) | pre | 69.8 ± 5.3 | 81.5 ± 2.4 | 86.5 ± 2.1 | 90.5 ± 1.6 | 93.0 ± 1.4 | 95.1 ± 1.1 | 96.2 ± 0.9 |
| post | 71.0 ± 7.8 | 81.6 ± 5.7 | 86.8 ± 4.1 | 90.5 ± 2.6 | 93.0 ± 2.2 | 95.2 ± 1.6 | 96.6 ± 1.4 | |
The number of modules is decided when the VAF exceeds 90% for the first time. VAF: variance accounted for
