Meta-Analysis Quiz

Steps in a meta-analysis include all of the following except:

• Analysis

• Abstraction

• Selection

A fixed effects model is most appropriate in a meta-analysis when study findings:

• Are homogenous

• Are heterogenous

• Either homogenous or heterogenous

• Neither homogenous nor heterogenous

Answer explanation

Yes...a fixed effects model is appropriate when the results of different studies are statistically homogenous, and a random effects model is better when they are heterogeneous.
