^aCampaign exposure index indicates self-reported exposure to no, 1, 2, or 3 or more campaign materials.

^bResults shown are from ordinal regression models that regressed the postcampaign response on the exposure index, with control for precampaign response. Comparable estimates and P values were obtained in ordinal regression models additionally adjusted for self-reported exposure to bogus campaign material and education.

*P < .05; **P < .01; ***P < .001.
