*Males collapsed with other/missing category to minimise risk of disclosure and to help maintain confidentiality.
**The “born abroad” risk group for HCV Research UK participants has been collapsed into the “other” category, because no equivalent risk group to “born abroad” exists in the Scottish clinical database. “Perinatal transmission group has also been collapsed into “other” to minimise the risk of disclosure and to help maintain confidentiality.
