^aAdjusted odds ratios from multivariable adjusted logistic regression models including all of the variables in the table; model estimates odds of patient responding “agree” or “somewhat agree” with statement: “If I could read my doctors’ notes, I would be concerned about my privacy” on the baseline survey.
