Randomized Controlled Trial
Canalith repositioning maneuver for benign paroxysmal positional vertigo: randomized controlled trial in family practice.
To determine whether the canalith repositioning maneuver (CRM) is effective for treating benign paroxysmal positional vertigo when it is used by family physicians in primary care settings. ⋯ A statistically significant proportion of patients in the CRM group returned to a negative response to the DH maneuver immediately after the first treatment. Family physicians can use the CRM to treat benign paroxysmal positional vertigo and potentially avoid delays in treatment and unnecessary referrals.

Randomized Controlled Trial
Diagnosing streptococcal sore throat in adults: randomized controlled trial of in-office aids.
To determine whether use of clinical decision rules or rapid streptococcal antigen detection tests (alone or in combination) can lower the number of unnecessary prescriptions for antibiotics for adults with acute sore throats. ⋯ Evidence-based clinical decision rules alone do not change family doctors' prescribing behaviour. Use of rapid antigen tests might allow physicians to persuade patients that negative results (and hence, viral infection) mean antibiotic therapy is not required.

Randomized Controlled Trial Comparative Study Clinical Trial
[Making a decision about hormone replacement therapy. A randomized controlled trial].
To compare the efficacy of a decision-making aid with an information document from the Society of Obstetricians and Gynaecologists of Canada (SOGC) with regard to decisions about hormone replacement therapy (HRT). DESIGN: Randomized clinical trial. SETTING: Quebec city region. PARTICIPANTS: Menopausal Francophone women 45 to 69 years old. INTERVENTIONS: Subjects were given a manual and an audiocassette describing a six-step approach to making a decision about HRT. MAIN OUTCOME MEASURES: Amount of anxiety over the decision (main outcome), general knowledge of the risks and benefits of HRT, personal expectations and values concerning these risks and benefits, and women's views on HRT. ⋯ The six-step approach to decision making was more helpful than the SOGC's information document in increasing subjects' knowledge of the risks and benefits of HRT, in creating more realistic expectations of HRT, and in increasing the congruence between subjects' personal values and their decisions on HRT.
