Table 3. Comparison of genotypic statistics using the E1 gene and the molecular epidemiology window (MEW).

Window	G+C content^a	Transition/transversion^a	Intergenotypic distance^a,b			Intragenotypic distances^a,c
			Range	Mean	Mean RGI vs RGII	RGI		RGII
			Range	Mean	Mean RGI vs RGII	Range	Mean	Range	Mean
E1	66.6	6.34	0.08~10.32	4.92	7.28	0.08~5.75	3.55	0~7.95	5.66
MEW	66.1	6.15	0~11.69	4.97	8.32	0~5.97	3.49	0~8.71	6.61

^aStatistics were determined from all sequences listed in Table 1. ^bThe range and mean of genetic distances (% difference) were determined by using all sequences. The mean rubella genotype I (RGI) vs. RGII was determined from all of the pairwise RGI-RGII combinations. ^cThe range and mean of genetic distances were determined for RGI and RGII viruses separately.
