Table 4 Association between energy and protein intakes and 28-day mortality as well as nutritional status stratified by days on exclusive nutritional support and GLIMPSE groups

From: The association between nutritional adequacy and 28-day mortality in the critically ill is not modified by their baseline nutritional status and disease severity
