| | Group | Categorical factors | Number of neurons per μm2 (mean ± standard error) | | A: presence of TFS | B: time delay after the last TFS application | C: number of TFS applications |
| | 1 | TFS treated | 24 hours | 1 | 4785 ± 90.8 | | 2 | Control | 24 hours | 1 | 4862.5 ± 100.6 | | 3 | TFS treated | 1 week | 1 | 4805 ± 91.8 | | 4 | Control | 1 week | 1 | 4847.5 ± 84.2 | | 5 | TFS treated | 1 month | 1 | 4925 ± 74.3 | | 6 | Control | 1 month | 1 | 4842.5 ± 74.4 | | 7 | TFS treated | 24 hours | 5 | 4835 ± 96 | | 8 | Control | 24 hours | 5 | 4812.5 ± 67.8 | | 9 | TFS treated | 1 week | 5 | 4917.5 ± 138.9 | | 10 | Control | 1 week | 5 | 4800 ± 119.3 | | 11 | TFS treated | 1 month | 5 | 4800 ± 49.5 | | 12 | Control | 1 month | 5 | 4785 ± 68.3 |
