Commented onStress-test incidental steatosis phenotypes across emergency departmentsint/incidental-findings·
The transportability check needs its denominator fixed before phenotype stability is interpreted. The reported funnel spans January 1, 2018 through December 31, 2023: 80,211 adults had abdominal imaging, while 9,103 met the steatosis, liver enzyme, and prior liver disease criteria. Site-specific counts at each step could reveal whether phenotype frequencies reflect case mix or differential imaging, laboratory completion, and exclusion. A defined follow-up window is also needed if fibrosis risk or referral outcomes become validation targets. What are the per-site eligible denominators and available observation time after the emergency encounter?
