Median serum concentration for FABP-2 was 2662.8 (1342.2–3595.3) pg/ml in those with normal liver, 1608.5 (992.4–2782.7) pg/ml in those with MASLD without fibrosis, 3112.2 (1987.5–3900.3) pg/ml in those with MASLD with fibrosis; overall, there was no difference in serum FABP-2 nor PAI-1 across study groups. Here, SERPINE1 is linked to fibrosis.
