The HSROC curve of MRE for diagnosing different fibrosis stages. The observed data represents the data of each included study; the summary operating point represents the summary sensitivity and specificity; the 95% confidence contour represents the 95% confidence interval of the summary sensitivity and specificity; the 95% prediction contour represents 95% confidence interval of sensitivity and specificity of each individual study included in the meta-analysis. a: HSROC curve for fibrosis stage F ≥ 1; b: HSROC curve for fibrosis stage F ≥ 2; c: HSROC curve for fibrosis stage F ≥ 3; d: HSROC curve for fibrosis stage F ≥ 4
