Hello Lydia, 

Thank you for your answer. I see 3 possibilities in case of multiple contrasts: considering them as separate studies, combining them or choosing the most pertinent to answer the meta-analysis question.
I have included studies with multiple contrasts (evaluating the same mechanism) for the same population. I guess it imply intra-study dependency between the results obtained for each contrast. In this particular case, don't you think that considering each contrast as an independent study could represent an important bias in my CBMA (for instance, inflating the true effect)?
 
As far as I understand the previous responses of developers to similar questions, combining different contrasts from the same study as not yet been implemented in the new version of SDM. For now, I choose to include only the most pertinent contrast from each study displaying multiple contrast. What do you think of this approach?

Best,

Layla
