Correlations between two established nutritional markers and the mPEW-S or original simple PEW score and (n = 144). a Correlation between mPEW-S and modified GNRI. b Correlation between mPEW-S and Cr index. c Correlation between the original simple PEW score and modified GNRI. d Correlation between the original simple PEW score and Cr index. Pearson’s correlation coefficients were used. The mPEW-S was used as continuous variable. Spearman’s rank-order correlation was used. A two-tailed P < 0.05 was considered statistically significant.
