Demographic data and further covariates.
| Variable | Patients |
HCs | p values | |
|---|---|---|---|---|
| InsL | InsR | |||
| No. | 30 | 22 | 19 | NA |
| Age (mean ± SD), years | 40.9 ± 8.5 | 41.6 ± 12.3 | 42.7 ± 11.7 | 0.845 |
| Sex ratio, F/M | 16/14 | 9/13 | 8/11 | 0.610 |
| Handedness, R/L, n | 26/4 | 17/5 | 19/0 | 0.092 |
| Scanner type, 3 T/1.5 T, n | 27/3 | 16/6 | 19/0 | 0.028 |
| Tumor volume, cm3 | 69.3 ± 34 | 51.1 ± 30.4 | NA | 0.048 |
Abbreviations: HC = healthy control; InsL = left insular glioma; insR = right insular glioma; L = left-handed; NA = not applicable; R = right-handed. The p values were determined by a one-way analysis of variance for age, a χ2 test for sex ratio, handedness and scanner type, and a t-test for tumor volume.
