Abbreviation: cGVHD = chronic GVHD.
A total PG-SGA score of 2 or above indicates the need for nutritional intervention, including patient and family education, symptom management including pharmacologic intervention, and appropriate nutrient intervention. For the component scores (weight summary, food intake, symptoms, activities and function, disease requirements, metabolic demand and physical), any deviation from zero indicates a deficit from optimal nutrition.
PG-SGA Global Assessment categories are based on clinician evaluation of patient’s weight, nutritional intake, nutrition impact of symptoms, functioning and physical exam. The categories are well-nourished, moderately malnourished or suspected malnutrition, or severely malnourished: for this study, groups were made of well nourished vs malnourished (moderately malnourished and severely malnourished).
