* P value comparing percent
RT-PCR-positive rate for all three goups was <0.01. Pvalue
comparing percent
PCR-positive for intravenous drug
users vs. others was 0.18. P-value comparing percent PCR-positive
for
blood transfusion participants
versus all others combine was ,0.01
**Odds of a participant bening PCR
positive if their risk factor is a blood transfusion versus the
odds for all
other groups combined
***P value comparing percent PCR-positive
if they were more than 40 years of age at estimated date of
infection
compared with if they were younger
than 40 years of age
****Odds of a participant being PCR
positive if they were estimated to have been infected before
1970
compared with after 1969
