Assessment of the severity of pruritus. Visual Analog Scale: 0% = no pruritus; 10%–30% = mild pruritus; 40%–60% = moderate pruritus; 70%–80% = severe pruritus; 90%–100% = very severe pruritus. 5D Itch Scale: The domain scores are added together, potentially ranging from 5 (no pruritus) to 25 (most severe pruritus). PBC-40: Items are scored from 1 to 5 (never, rarely, sometimes, most of the time, and always), and the individual item scores are summed to give a total domain. Abbreviation: PBC, primary biliary cholangitis.
