What are common biases in meta-analysis?

Common biases in meta-analysis include publication bias, selection bias, and reporting bias.

Can you explain publication bias?

Publication bias occurs when studies with positive results are more likely to be published than those with negative or inconclusive results.

How can researchers minimize these biases?

Researchers can minimize biases by conducting comprehensive literature searches, including unpublished studies, and using statistical techniques to adjust for bias.

Are there tools to help identify these biases?

Yes, tools like the Cochrane Collaboration's Risk of Bias tool can help assess the risk of bias in studies included in a meta-analysis.
