Study Overview
=================
Brief Summary
-----------------
This is an multicenter, randomized, double-blind, parallel-controlled study to evaluated the efficacy of pioglitazone hydrochloride and metformin hydrochloride tablets on the patients with newly diagnosed type 2 diabetes mellitus combined with non-alcoholic fatty liver disease.

Detailed Description
-----------------
Taking metformin monotherapy as a control, we evaluated the efficacy of pioglitazone hydrochloride and metformin hydrochloride tablets on hepatic fat ultrasound and liver enzyme levels, and observed whether the drug can improve fatty liver in patients with newly diagnosed type 2 diabetes combined with non-alcoholic fatty liver disease. This is an multicenter, randomized, double-blind, parallel-controlled study.
