Relationship between rate of gastric emptying and fasting cholecystokinin and peptide YY concentrations. Relationship between the rate of gastric emptying (measured using an isotope breath test and calculated as the gastric emptying coefficient (GEC); greater number, more rapid emptying) and (a) fasting cholecystokinin (CCK) concentrations (r = -0.33; P = 0.04) and (b) fasting peptide YY (PYY) concentrations (r = -0.36; P = 0.02) in 39 critically ill patients.
