P value is the level of statistical significance for between group comparisons to the bilateral vestibular hypofunction (BVH) group.
The Dizziness/Imbalance group includes all who reported a problem with dizziness or balance in the preceding 12 months.
Percentages are adjusted to represent the U.S. population based on the weights supplied by NHIS to correct for the complex survey design.
