What this record shows
Almost everything reported here is food and beverage — 97.1% of the total across 174 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 19 manufacturers reported payments, led by AbbVie at 31.3% of the total. Reporting peaked in 2019 at $1,569 and has fallen 98.6% since, to $21 in 2024. That places this record below the midpoint for gastroenterology clinicians in CT, where the typical reported total is $3,356.
