Figure 2 Triage based on non-invasive tests for overall study population. From the study population of 3669 patients, 75 (2.0%) were identified who satisfied all the parameters of our algorithm: elevated alanine aminotransferase value, elevated fibrosis-4 score ≥ 1.3, and elevated FAST score > 0.35. ALT: Alanine aminotransferase; FIB4: Fibrosis-4.
