^*Estimates of association are hazard ratios (95% CI) from PWP-TT models, corresponding to the risk of each type of hospital admission per SD decrease in grip strength.

^**Estimates of association are relative risks (95% CI) from log-binomial regression models, corresponding to the risk of each type of hospital admission per SD decrease in grip strength.

Unadj and Adj indicate whether or not models were adjusted for potential confounding variables. Adjusted models accounted for age, height, weight for height residual, smoking status, alcohol consumption and social class
