Meta-analysis results. a Regions showed lower GM in AUD patients than controls. b Meta-regression analysis indicated that GM in the right insula was significantly negatively associated with duration of abstinence in AUD patients. c Meta-regression analysis indicated that GM in the right insula was significantly negatively associated with mean age in AUD patients. d Meta-regression analysis showed that GM in the left middle frontal gyrus was significantly negatively associated with male ratio in AUD patients. Blue colour represents GM reduction
