Amulticenter double-blind randomized study was carried out to compare the effect of drug x with that of a placebo in patients surviving acute myocardial infarction (ami). treatment with the drug started 7 days after infarction in 1,884 patients, which are 52% of all persons who were evaluated for entry into the study. 945 participants were randomized to treatment with drug x while 939 were assigned to the placebo group. patients were then followed for 12 months for reinfarction. there were 152 deaths in the placebo group and 98 in the group receiving drug x. a preliminary analysis was conducted after 6 months and found that 87% of participants in the placebo group and 80% of those in the drug x group had taken more than 90% of their prescribed dosages. which statement best describes this finding? group of answer choices the study will find a decreased effect of ami prevention in the drug x group since fewer participants complied with the prescribed treatment the characteristics of patients who failed to comply with the treatment dosages should be assessed as they may differ from those who complied the researchers should consider a crossover design in order to calibrate the compliance rates between each group randomization failed to ensure an equal likelihood of compliance with treatment
