GPT and gallstones: 524 patients (373 males) were selected, and gallstones were diagnosed in 20% (108) and NASH was diagnosed in 60% (313) via liver biopsy. The diagnosis of gallstones increased with increasing fibrosis (p=0.0001) and with severity of necrosis and inflammation (p=0.01). OR=1.37(95%CI=1.04-1.8) for gallstones and female gender. OR=1.027(95%CI=1.003-1.05) for gallstones and age. OR=1.21 (95%CI=1.10-1.33) for gallstones and fasting glucose. OR=1.40(95%CI=1.06-1.89) for gallstones and NASH. ALT levels had a lower risk of gallstones as the OR=0.98(95%CI=0.97-0.99).
