Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 89 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 24 manufacturers reported payments, led by GSK at 30.0% of the total. Among pediatrics clinicians in TX with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.
