Table 2 Comparison of goal and achieved energy and protein intakes between 28-day survivors and nonsurvivors stratified by days of exclusive nutritional support

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
