Studies that did not test the peptide alone1

In this study, Pramlintide (Symlin) was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Pramlintide (Symlin).

  1. 06HumanNot a test of Pramlintide (Symlin) aloneOther designMechanism

    In a human pramlintide dose-response study, mean pancreatic polypeptide in the first postprandial hour correlated with gastric emptying half-time; the source calls it inverse but reports R(s) = 0.48 (P = 0.044).

    In plain wordsIn the human pramlintide study, pancreatic polypeptide and stomach emptying time were linked. The source calls it inverse but gives a positive coefficient.
