GPT and Abdominal obesity: When Ln ALT/AST ratio increased 0.1 unit increment, B values were 0.056 (95% CI 0.051–0.060) in total subjects, 0.051 (95% CI 0.046–0.056) in subjects without central obesity and 0.061 (95% CI 0.053–0.068) in subjects with central obesity, respectively, about 10 times smaller than those of every 1 unit increment (Table 3).
