Hello, I would need the help of a qualified and rigorous statistician to perform a meta-analysis of 30 scientific papers in the field of cardiology. 30% of these empiric studies reach a conclusion , while 70% of them reaches the opposite conclusion. I would like to compare these two groups of studies in terms of sample size, participants ‘ characteristics, methods used etc. The aim is to see if there are methodological biases that could explain these opposite conclusions. Or, we could pool the articles to integrate the results of these studies and come to a single and more accurate conclusion.
The analysis has to be performed with R studio, and I need to be provided with all codes and files used. The hired statistician also has to be available for explication if needed.
Thank you very much!
