Im currently working on a meta-analysis of interventional randomized controlled trials.
In the protocol, I mentinoned that I will be using Review Manager 5 for both the analysis and assesement of publication bias.
However, after the analysis, I noted that there is asymmetry of the funnel plot, indicating potential publication bias.
Now I would like to confirm the publication bias and correct the effect with trim-fill method.
In Review Manager, there is no way to do this, so I have to do another software like JASP.
My question is: Is using another software a violation of the protocol of the study?
If not, how should I report this? Should I just mention that I will be using JASP instead of Review Manager in the method?
