This is an aspect of confounding (see quasi-experimental design below) Understand the difference between a statistically significant difference (most commonly seen when the p value is less than . 05) and clinically meaningful (a meaningful change, usually greater than the mdc and/or mcid) Clinical equipoise-the state of genuine uncertainty as to the advantages or disadvantages of each therapeutic aim in a clinical trial. Experimental design: key aspect of experimental design is that is the best way to determine causality (see below) Study type identification: be able to identify and know the differences between the following types of studies. This is partially carried over from the first half of class, as it is an important skill.
