What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Ingesting coffee without creamerOther
Ingesting coffee without creamer and evaluating gastric emptying with gastric ultrasound at different time points.

What is being measured
The primary outcome is the main question the study is designed to answer.
Gastric emptying times of liquids at set volumes.
Measured: Study participants have a baseline ultrasound to confirm if stomach was empty and then have scans every hour after ingesting coffee until stomach was empty (Grade 0) or 4 hours maximum, whichever occurs first.

- Once eligibility was established, participants were randomly divided into 2 groups: one group assigned to drink 16 ounces of cold black coffee without creamer and the other group assigned to drink 16 ounces of cold black coffee with two standard creamer pods (0.76 oz) added. Randomization was generated by alternating participants between receiving black coffee or coffee with creamer after they had been consented for the study.
