In the original publication, the measurement units for Glucagon-Like Peptide-1 (GLP-1) are given incorrectly. The units should read pmol/liter instead of pmol/ml. The error appears on page 1763 of the publication (page 3 of the manuscript) at the bottom of the second column, in Table 3, and in Figure 3.
