Table 2.
Characteristics of the two vestibular migraine subgroups (VM1, VM2) identified in Fig. 3A (DHI versus tilt threshold).
| Clinical measure | VM1 | VM2 | Statistical comparisons |
|---|---|---|---|
| DHI | 32.1 +/− 4.6 | 31.7 +/− 4.6 | t-test: p = 0.47 |
| *MSSQ | 30.0 +/− 3.1 | 19.7 +/− 3.4 | t-test: p = 0.02 |
| HIT | 55.2 +/− 1.9 | 56.0 +/− 2.1 | t-test: p = 0.40 |
| Age (years) | 38.9 +/− 3.3 | 34.0 +/− 3.4 | t-test: p = 0.17 |
| Sex (F:M) | 9 F:3 M | 11 F:2 M | Rank test: p = 0.5 |
| *Roll tilt threshold (deg) | 1.94 +/− 0.17 | 1.01 +/− 0.04 | M-W RST: p < 0.001 |
Abbreviations are defined in the Table 1 legend; roll tilt thresholds were measured at 0.05 Hz. All values are shown as means +/− one SEM. M-W is Mann-Whitney and M-W RST is rank sum test. Asterisks indicate clinical measures that differ between VM1 and VM2.
