SNR=single non-reactive; MNR=multiple non-reactive; REAC=reactive at first test; SERO=seroconverter.
¹The serological groups are not mutually exclusive, i.e., over time an individual may fall into more than one group.
²The N for 12 month lagging accounts for removal of those subjects who were not followed for a minimum of 12 months or who died within 12 months of their first anti-HCV test. Those subjects excluded by 12 month lagging did not form part of the standardized mortality and hazard ratio analyses.
