The strength of recommendation against routine, long-term use of vitamin E to prevent heart disease, based on the best available evidence, should be: a 1 b A c 2 d B 9 A new drug increases the forced expiratory volume in one second (FEV1) and peak flow rate in patients with an acute asthma exacerbation. Data on symptom improvement is lacking. The strength of recommendation in favor of using this drug is: a 3 b B c C d 2 10 In order to assign a level of evidence of 1 to a randomized controlled trial with primarily patient-oriented evidence, what criteria is considered in addition to blinding (if feasible) and adequacy of power (sample size) and follow-up ( 80%)? Whether: a Allocation is concealed b Data is analyzed as per protocol c A and B d None of the above
