If the group getting the drug did much better than the group with the sugar pill, it would indicate that the drug was more effective than the sugar pill. This is the purpose of conducting scientific experiments with a control group, to compare the effects of a treatment against a placebo or other standard treatment. While a theory or hypothesis may be formed based on the results, the primary conclusion would be that the drug was effective. The control group would not have improved because of the drug, as they were given a sugar pill and not the actual drug being tested.
