Question 1

What does a high P-value (>0.1, maybe >0.08) tell you if you are conducting a statistical test for heterogeneity

Answer 1

High P-value means that the null hypothesis (that the estimate of effect is the same of all studies) cannot be rejected.

This means that there is low heterogeneity among the studies in your systematic review => they can be combined in a meta-analysis

Yay!

Question 2

What is the random effect model for a systematic reveiw?

Answer 2

A systematic review/meta-analysis that assumes that the included studies ask the a slightly different, but closely-related question. Results can be combined, but generally there is more heterogeneity than in the fixed-effect model

Used more frequently

Question 3

What is the null hypothesis in a test for statistical heterogeneity?

Answer 3

The estimate of effect is the same in all studies
