ALB and malnutrition: We stratified study participants by serum albumin cut at 4.0g/dl to analysis the effect of the interaction between malnutrition-inflammation and fluid overload on handgrip strength, and high fluid status was still associated with poor upper extremity muscle endurance (β = -91.42, P = 0.001 in high serum albumin group; β = -72.43, P = 0.01 in low serum albumin group).
