PSS001104 All individuals had type 2 diabetes (T2D). Diabetes was defined as individuals having either of following criteria: 1) self-reported type 2 or unspecified diabetes (codes 1220 and 1223 in data-field 20002); 2) ICD10 diagnoses codes E11 and E14 (data-field 41270); 3) insulin treatment or use of oral glucose lowering drugs (data-fields 6153, 6177 and 20003); 4) serum glucose level ≥11.1 mmol/L (200mg/dL); 5) HbA1c ≥ 48 mmol/mol (6.5%). Cases were individuals with hepatocellular cancer (HCC). HCC was defined by combining International Classification of Diseases, Tenth Revision (ICD-10) code C22.0 from both UK cancer registry (data-field 40006), and hospitalization records (data-field 41270). —
