Data are shown as mean ± SD. Group N: normal ALT and liver echogenicity; group A: elevated ALT and normal liver echogenicity; group E: normal ALT and abnormal liver echogenicity; group AE: elevated ALT and abnormal liver echogenicity.
* P < .05 against group N.
† P < .05 against group A.
‡ P < .05 against group E.
§ P < .05 against group AE.
‖ The retrospective power of one-way analysis of variance was calculated using SPSS general linear model procedures.
BMI: body mass index; SBP: systolic blood pressure; DBP: diastolic blood pressure; FPG: fasting plasma glucose; TC: total cholesterol; HDL-C: high-density lipoprotein cholesterol; LDL-C: low-density lipoprotein cholesterol; Log TG: log transformation of triglyceride.
