What are the commands and software used for dose-response meta-analysis in STATA 17.0? Also, what considerations are there for data extraction in dose-response meta-analysis?
To conduct a dose-response meta-analysis in STATA 17.0, you can use the "mvmeta" command. Here's a step-by-step guide on how to perform a dose-response meta-analysis in STATA:
Data Preparation: Make sure your data is appropriately formatted with the exposure levels, outcome data, and other relevant covariates.
Install Required Package: If you haven't installed the "mvmeta" package, you need to do so first. You can install it using the following command: ssc install mvmeta
Use the "mvmeta" command to perform the analysis. Below is the general syntax: mvmeta effect_var [varlist]
effect_var is the effect estimate variable (e.g., log odds ratio, hazard ratio, risk ratio).
[varlist] is a list of variables containing the dose or exposure levels.
Also you can simply perform meta-regression and Bubble plots which are included in the STATA itself. You need to extract the does of the intervention or exposure for each study and then perform a meta regression and bubble plot which will show you the association of dose and assessed outcome perform in your study.
