Interpret this confidence interval for an effect size: 3.2 (0.76, 6.9)

Should be statistically significant because it does not contain the value 0

When looking at any type of ratio (LR, Odds, Hazard, RR, etc), if the value = 1, what is your interpretation?

No difference, results could have occured by chance.

Which is NOT a best practice for conducting a systematic review?

Limit searches to free articles and English only

amount of change that just exceeds the SEM

What is a 2 X 2 contingency table?

Compares 2 groups with a dichotomous dependent variable

What is sampling (selection)?

process of how subjects are chosen from a potential pool

All are steps in creating a clinical prediction rule except

Selecting the inclusion and exclusion criteria

A forest plot is typically found in
