CKB and metabolic dysfunction-associated steatotic liver disease: For non-alcoholic fatty liver disease, a meta-analysis of six cohort studies with 32 657 cases showed a 21% lower risk comparing high and low categories of physical activity, with similar associations for total and leisure-time physical activities.14 In CKB, the finding for total physical activity was consistent with previous studies, whereas there was no clear association for leisure-time physical activity (online supplementary figure 11).
