I am doing the meta-analysis in which there are some studies which are only in patients who need emergent repair and then there are some studies which provide the data of elective repair type only. Can we pool the data of both emergent and elective repair type together or not?
Typically you can not pool data from both type of studies as it has different underlying conditions and heterogeneity.
but if you want to consider this option you can approach it considering your research question in different manner like SUBGROUP ANALYSIS, MODERATOR ANALYSIS or SENSISTIVITY ANALYSIS.
By avoiding pooling emergent and elective repair data and considering alternative approaches, you can ensure a more robust and informative meta-analysis.
Always consult with a statistician familiar with meta-analysis techniques for guidance on the most appropriate approach for your specific research question Muhammad Ahmed
