PRL and metabolic dysfunction-associated steatotic liver disease: Remarkable improvements in discrimination were confirmed by the IDI (0.196; 95%CI, 0.052–0.340; P = 0.008 for males and 0.262; 95%CI, 0.090–0.434; P = 0.003 for females), suggesting further average separation of NAFLD from non NAFLD by adding PRL.
