Three variables, BMI, HOMA-IR and NAFLD score, all showed positive correlations with palmitoleic acid (C16:1n-7), oleic acid (C18:1n-9), dihomo-γ-linolenic acid (C20:3n-6), SCD1(16) (C16:1n-7 /C16:0), and the Δ6 (C20:3n-6/C18: 2n-6) index, and negative correlations with linoleic acid (C18: 2n-6), and the Δ5 (C20:4n-6 /C20: 3n-6) index. This evidence concerns the gene SCD and metabolic dysfunction-associated steatotic liver disease.
