Deep-learning analysis suggests a facial image signal associated with low muscle mass in a clinical cohort enriched for chronic liver disease: a proof-of-concept study

Background Sarcopenia is a clinically relevant complication of chronic liver disease. Because changes in muscle mass, adiposity, and nutritional status may affect facial morphology, this exploratory study examined whether standardized frontal facial photographs contain an algorithmically detectable signal associated with low measured muscle mass. Methods Prospectively collected clinical data and f…
