the propranolol group had a lower cumulative probability of experiencing recurrent resting angina than the placebo group ( p = .013 ) , and over the first 4 days of the trial the mean number of clinical episodes of angina ( propranolol 0.9 +/- 0.2 , placebo 1.8 +/- 0.3 , p = .036 ) , duration of angina ( propranolol 15.1 +/- 4.3 min , placebo 38.1 +/- 8.4 , p = .014 ) , and nitroglycerin requirement ( propranolol 1.1 +/- 0.3 tablets , placebo 3.5 +/- 0.8 , p = .003 ) were also fewer .
