It means there's a 6% chance the conclusion's bad. 0.05 is the usual cutoff. In this case though the drug effect is about equal to the sugar pill, but the sugar pill crew(<79>) did better than the drugged up crew(<(58+65)/2=62>).
I’m sorry. I was being sarcastic. When you see those adverse effects from the other drugs, ugh. I thought they had some evidence for using antipsychotics in folks who were not psychotic, e.g. demented.
