^aThe malnutrition-inflammation scale (MIS) is a 10-component scale with a higher score reflecting a more severe degree of malnutrition and inflammation status
^bUnivariate variables with P values < 0.05 were entered into the multiple linear regression
^cNominal variables were entered into analysis using dummy coding
^dAn unstandardized coefficient (B) represents the amount of change in a dependent variable (i.e. MIS score) due to a change of 1 unit for each of independent variable
^eA standardized coefficient (Beta) compares the power of the effect of each individual independent variable to the dependent variable. The independent variable with a higher absolute value of beta coefficient has a stronger effect
^fP values are bold where they are less than the significance level of 0.05
