All results are adjusted for weights and survey design to produce nationally representative estimates; the unweighted sample included 918 visits for PWD and 26,543 visits for PWOD. For all percentages, the denominator is total number of visits. The only exception is for the number of repeat visits in the past 12 months: since this information is only available for the sampled physician’s practice, this variable is presented separately for primary care and non-primary care clinics, and the denominators in those cases refer to the total number of visits involving a primary care physician or visits involving a non-primary care physician. Pearson Chi-squared tests were used for categorical variables and t-tests for continuous variables.
