Non-osteotomy group | Osteotomy group | |||||
---|---|---|---|---|---|---|
Group A1 (n=67) | Group A2 (n=52) | P value | Group B1 (n=27) | Group B2 (n=42) | P value | |
EP events | MEP (2), SSEP+MEP (1) | SSEP (1) | – | MEP (13), SSEP+MEP (3) | MEP (12), SSEP+MEP (2), SSEP+MEP+DNEP (7) | – |
Number of EP events | 3 | 1 | 0.443 | 16 | 21 | 0.452 |
Number of MEP change | 3 | 0 | 0.122 | 16 | 21 | 0.452 |
All-channel positive number | 1 | 0 | 0.376 | 3 | 7 | 0.522 |
