A prospective cross‐sectional‐comparative analysis of nutrition screening and assessment tools in chinese nasopharyngeal carcinoma inpatients undergoing radiotherapy using Global Leadership Initiative on Malnutrition criteria as the gold standard

Therefore, NRS-2002 could be a more appropriate choice for initial nutrition screening in the diagnostic framework of GLIM for individuals afflicted with nasopharyngeal cancer, both before and after radiotherapy. The alignment of GLIM criteria with PG-SGA in identifying undernourished patients varied from slight to moderate.
