Long-term Follow Up of Patients in the Birmingham and Lambeth Liver Evaluation Strategies (BALLETS) Study

This study will follow-up a cohort of patients from the Birmingham and Lambeth Liver Evaluation Strategies (BALLETS) study using a database search based on their individual National Health Service (NHS) numbers. The investigators will interrogate the Hospital Episode Statistics database and the Office of National Statistics database, and examine three categories of end points: death, inpatient attendance primarily due to liver disease, and outpatient attendance primarily due to liver disease. A logistic regression analysis will then be conducted to determine associations between these end points and the presence, and degree, of fatty liver in the original BALLETS study, adjusted for age, sex, alcohol intake, BMI, and baseline ALT measurement.
