CCN2 and metabolic dysfunction-associated steatotic liver disease: The concentrations of CTGF in cases of moderate (NAFLD score of 3–4) and high (NAFLD score ≥ 5) NAFLD activity (n = 16) were higher than those in cases with no or low NAFLD activity (NAFLD score < 3) (n = 11) (t = 3.971, P = 0.001; Fig. 6B).
