| Controlled Oral Word (BL) | 46.0 (11.6) | 40.4 (11.9) | 0.24 |
| 1 day postoperative | 51.8 (11.4) | 39.1 (12.2) | 0.01 |
| Rey Copy (BL) | 29.0 (4.3) | 29.0 (5.0) | 0.99 |

| Trails A (BL) | 47.0 (16.5) | 43.8 (15.9) | 0.63 |
| 1 day postoperative | 41.6 (14.0) | 51.0 (18.6) | 0.13 |
| Trails B (BL) | 101.8 (36.3) | 91.25 (37.3) | 0.48 |
| 1 day postoperative | 89.0 (34.8) | 187.8 (153.8) | <0.001 |
a
SD, standard deviation. Increasing values demonstrate improved cognitive performance for Boston Naming, Controlled Oral Word, and Rey Copy. These test scores are unitless. However, decreasing values in seconds show improved cognitive performance for Trails A and Trails B.
