Figure 2.

The impact of various admission diagnoses on gastric emptying variables, (a) t50 and (b) GEC, in critically ill patients. The bars represent median values of the gastric emptying variables. ^#P < 0.05, versus cardiac injury and non-gastrointestinal (GI) post-operative respiratory failure; ^##P < 0.01, versus cardiac injury and non-GI post-operative respiratory failure. GEC, gastric emptying coefficient; t50, gastric half-emptying time.
