Hypothesis*: That DTCA would result in: | DV | N (% of Total Population)† [95% CI] | Significant Associations (see text for details) |
---|---|---|---|
Clinical benefits and harms | |||
More patients attending physicians for preventive health care. | Respondent requested preventive care from a health professional Respondent attended physician or other health professional for a check-up | 203 (6.3%)[5.3–7.5%] 189 (5.9%)[5.0–6.9%) | Low education, Hispanic, chronic disease Low education, Hispanic, chronic disease |
