However, a 2008 analysis of the Austronesian Basic Vocabulary Database[1] found no support for a northern Sumatran family. Toba Batak and Gayo were found to fit in different branches of an expanded Malayo-Sumbawan family (along with other Sumatran languages), whereas Nias appeared to be closest to Central–Eastern Malayo-Polynesian, though these outside connections were only moderately supported (85% confidence). Enggano was not considered, and it is not clear that language is even Austronesian.
