A pharmaceutical company claims that its new drug is effective because, in a trial, 80 percent of patients reported feeling better. The trial included no control group receiving a placebo.
The trial is flawed because it fails to:
- Establish how much improvement would have occurred even without the drug's active effect.
- Verify that the patients enrolled were representative of the broader population.
- Take into account that the drug might produce harmful side effects.
- Spell out the biological mechanism by which the drug improves health.
- Confirm that the drug works equally well in every demographic group.
