Comparison of results of Chinese CRF01_AE strains intrasubtype analysis between different background areas (mainland China vs all over the world)

Background area	No. of sequences from China	Sequences inferred as recombinant	Rate
Mainland Chinaa	153	16	10.5 %
Worldwideb	153	84	54.9 %

^aPerformance of intrasubtype recombination analysis of CRF01_AE sequences in mainland China under the background of mainland China, i.e., the background of 153 sequences

^bPerformance of intrasubtype recombination analysis of CRF01_AE sequences in mainland China under the background of all over the world, i.e., the background of 339 sequences
