aClasses: 1 (negative or positive to antigens of the GP50 protein family); 2 (positive to antigens of the protein T24-42 protein family, with or without GP50); 3 (positive to antigens of the GP50, T24-42, and 8 kDa protein families); and 4 (positive to antigens of the GP50 and T24-42 protein families and strongly positive to antigens of the 8 kDa protein family).
bMean ± standard deviation.
