RMST, restricted mean survival time; RMST model was adjusted by baseline age, Townsend Deprivation Index (TDI), ethnicity (White, Asian or Asian British, Black or Black British, and other), education qualifications (degree or no degree), physical activity (low, moderate and high level), smoking status (current, former, or never), alcohol status (current, former, or never), vegetables consumption, fruits consumption (0–1, 2–3, and ≥ 3 pieces per day), red meat consumption (never, less than once a week, once a week, and more than twice a week), processed meat consumption (never, less than once a week, once a week, and more than twice a week), and oily fish consumption (never, less than once a week, once a week, and more than twice a week), coffee (continuous), and dairy (yes or no). Normal group consisted of those without sarcopenia, obesity, or sarcopenic obesity
