2.5. Outcome Assessment
NAFLD
HEPATIC STEATOSIS
The controlled attenuation parameter score (CAP) was applied to measure and quantify hepatic steatosis. CAP measures the rate of ultrasound attenuation (due to liver fat) at the standardized frequency of 3.5 MHz through vibration-controlled elastography (VCTE). Following the literature, cut-off points were set at <248, 248–267, 268–279, and ≥280 dB/m for absent, mild, moderate, or severe NAFLD, respectively [
