The inverse effect of meal intake on controlled attenuation parameter and liver stiffness as assessed by transient elastography.

Following a meal, patients' CAP values declined with the peak value at 60 min, contrasting with the rising of LS values with the peak value at 15 min. The post-meal CAP and LS values returned to baseline by 150 min. A fasting period of more than 150 min after a meal is recommended for patients undergoing TE.
