aRepresents the estimated probabilities of HCV prevalence in male and female in different age groups calculated using the inverse transformation of logistic regression model. bAverage probability of six age groups of both genders. cThe goodness of fit tests Pearson, deviance, and Hosmer-Lemeshow for the model have p values ranging from 0.312 to 0.724 indicating the logistic regression model fit adequately HCV prevalence data. dCI (Confidence Interval) for male gender was 1.10 (0.83-1.46) with p value 0.497.

Distribution of positive & negative in gender as well as age groups based criteria.
