| Evoked potential monitoring | No. of study | No. of patients | Best-case scenario DTA estimates (% (95% CI)) | Worst-case scenario DTA estimates (% (95% CI)) | ||
| Sn | Sp | Sn | Sp | |||
| SSEP | 10 | 1262 | 63 (49 to 75) | 100 (91 to 100) | 50 (30 to 69) | 81 (66 to 90) |
| MEP | 5 | 1152 | 74 (55 to 87) | 100 (90 to 100) | 59 (41 to 76) | 93 (89 to 95) |
| SSEP and MEP | 3 | 201 | 94 (80 to 99) | 100 (98 to 100) | 89 (52 to 100) | 83 (71 to 92) |
DTA, diagnostic test accuracy; MEP, motor evoked potential; Sn, sensitivity; Sp, specificity; SSEP, somatosensory evoked potential.
