Many thanks indeed. The reference is very useful. I do appreciate your kindness and your help.
What method we can call this in the statistical methods please.
All the best,

Homa,
I assume that you want to compare 'B or C' vs 'A', the following article describes approaches to aggregate data from a multi-arm study (you find a worked example in section 4.1):
R?cker G, Cates CJ, Schwarzer G. Methods for including information from multi-arm trials in pairwise meta-analysis. Res Synth Methods.
2017;8(4):392?403.
Best wishes
Guido
