From this analysis, it is evident that GFN2-xTB and GFN1-xTB are the most co-cited approaches. One possible explanation for this could be that a significant portion of these cocitations come from papers related to method development and benchmarking. The same reasoning can be applied to the regular co-citation of GFN-FF with xTB methods, with GFN2-xTB being cited in approximately half of all GFN-FF cited works.
