Does St. John wort (an herb) have a siginifact effect in treating major depression? A study looked at 340 adult outpatients suffering as measured by their HAM-Dscore, randomly assiging each subject to either a placebo, St.John's wort, or a second active treatment for comparison. The study found the diiference in treating major depression as measured by improvement in HAM-D scores between St.John's wort and the placebo was not statistically significant This means that: A. a difference this big could easily occur just by chance even if St. John's wort does not better than the placebo B. We cannot make a 95 percent confidence statement C.The placebo makes no difference in the subjects' depression D. The study was badly designed
