Spearman’s rank correlation coefficient showed a weakly significant negative correlation between age at surgery and the AGR (ρ = − 0.25, P < 0.01).
Spearman’s rank correlation coefficient showed a weakly significant negative correlation between age at surgery and the AGR (ρ = − 0.25, P < 0.01).
A low AGR may thus reflect the degree of poor nutritional status (hypoalbuminemia) and tumor progression (hyperglobulinemia) in a more sensitive manner than either measure alone and may therefore serve as a highly significant prognostic biomarker.
