^{a}Represents the estimated probabilities of HCV prevalence in male and female in different age groups calculated using the inverse transformation of logistic regression model. ^{b}Average probability of six age groups of both genders. ^{c}The 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. ^{d}CI (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.
