              Note: A PR of > 1 indicates that the ratio of females reporting a specific sexual practice exceeds that of males. For example, self-reported inconsistent condom use was 61% more prevalent among
              females than males, whereas a PR of < 1 indicates that fewer females reported the practices compared to males.
              CI, confidence interval; PR, prevalence ratio.
