A randomized double-blind study of the effect of Botox and Dysport/Reloxin on forehead wrinkles and electromyographic activity.

Methods. We surveyed 50 new adult patients attending a dermatology clinic visit for various dermatologic conditions. The 25 patients in the intervention group received a short brochure containing information about their dermatologist’s training, desire to provide high-quality health care, and contact information; 25 control patients did not receive the brochure. Both groups completed a postvisit survey of 6 questions related to patient demographics, including age, sex, ethnicity, education, payment source, and reason for their office visit. They also completed 11 items related to their experience, satisfaction, and comfort level during their visit, each item rated on a numerical scale on which 0 indicated “strongly disagree” and 10, “strongly agree.” The survey was analyzed using t tests and corresponding means; P values were then calculated.
