How to perform a meta-analysis of regression coefficients?

How to perform a meta-analysis of regression coefficients? I want to perform a meta-analysis but the included studies use different models to analyze the data.

Are there any studies that use correlation coefficients?

There are Pearson correlation (3 studies), Spearman correlation (1 study) and several studies (~7-10) with regression coefficients (linear regression, weighted least squares regression, multivariate regression, and so on). What would be preferable (and possible): a) to use the correlation coefficients.

How are beta coefficients used in a meta-analysis?

On the use of beta coefficients in meta-analysis This research reports an investigation of the use of standardized regression (beta) coefficients in meta-analyses that use correlation coefficients as the effect-size metric.

When do you use a multivariate regression model?

When there is more than one predictor variable in a multivariate regression model, the model is a multivariate multiple regression. Please Note: The purpose of this page is to show how to use various data analysis commands. It does not cover all aspects of the research process which researchers are expected to do.

How many studies are included in a meta-analysis?

I want to perform a meta-analysis but the included studies use different models to analyze the data. There are Pearson correlation (3 studies), Spearman correlation (1 study) and several studies (~7-10) with regression coefficients (linear regression, weighted least squares regression, multivariate regression, and so on).

Is it possible to analyse regression coefficients with standard errors?

It is perfectly possible to analyse the regression coefficients as long as you have their standard errors. If the authors of the primary studies have given a confidence interval you can use it to back-calculate the standard error.

What is the p value of meta regression?

The P value of each regression coefficient will indicate whether this difference is statistically significant. Meta-regression may be performed using the ‘metareg’ macro available for the Stata statistical package.

How is meta regression used in subgroup analysis?

Meta-regression can also be used to investigate differences for categorical explanatory variables as done in subgroup analyses. If there are J subgroups membership of particular subgroups is indicated by using J – 1 dummy variables (which can only take values of zero or one) in the meta-regression model (as in standard linear regression modelling).
