N.S. denotes not significant; OLR, ordered logistic regression.* = p 6. Positive changes denote improvement on the 10-grade scale used in Table 1.7. Patients graded the outcome on a 10-grade scale where 10 corresponded to a very good outcome and 0 to a very poor one.8. The air-bone gap is the average difference between air conduction thresholds and bone conduction ones at the frequencies 0.5, 1, 2, and 3 kHz. Data are means ± 95% CI.Changes in scores for tinnitus, dizziness, and other variables.
