  • Incomplete or absent datasets are indicated with a hyphen (-).

  • Data on number of patients, concurrent autoimmune hepatitis (AIH) diagnosis, percentage of women and mean age for the cohorts from each hospital is shown where available.

  • *Indicates hospitals with dedicated hepatology clinics. Hospitals with general gastroenterology clinics are unmarked.

  • †The patient list was obtained in December 2017, however, data collection was delayed due to staffing disruption. Data collection in 2020 was undertaken using the same list of patients obtained in 2017 to ensure consistency with other datasets.

  • ‡Data on sex were absent for seven patients who were therefore omitted from the percentage calculation.

  • AIH, autoimmune hepatitis; NHS, National Health Service.
