The discrepancy between these results may have various explanations: (1) our main objective was to associate GLP1 with osteoporosis, not directly with BR markers; (2) postmenopausal osteoporosis is a bone disorder with intense BR43, increasing all BR markers, with a final predominance of bone resorption; and (3) we studied postprandial levels of peptides but fasting values of BR parameters, and GLP1 secretion likely changes in response to food intake. Here, GLP1R is linked to osteoporosis.
