IGF1 and metabolic dysfunction-associated steatohepatitis: When 15 patients with NASH were analyzed according to the grade of inflammation, IGF-1 expression decreased with advanced grade of inflammation; however, statistical significance was missed due to low sample size (IGF-1/GAPDH cDNA ratio: grade of inflammation 1 (n = 2): 2.07 ± 2.40; grade of inflammation 2 (n = 9): 0.91 ± 1.01, grade of inflammation 3 (n = 4): 0.41 ± 0.26; p = 0.25).
