چکیده
1. (Taken from [1]) A statistical analysis that combines information from several studies is called a metaanalysis. A meta-analysis compared aspirin with placebo on incidence of heart attack and of stroke, seperately for men and from women (J. Am. Med. Assoc., 295: 306-313, 2006). For the Women’s Health Study, heart attacks were reported for 198 of 19,934 taking aspirin and for 193 of 19,942 taking placebo. We are interested in whether aspirin was helpful for reducing the risk of heart attack.
