Outcomes of meta-analysis; the results indicate the final accuracy of TE at different stages of fibrosis; for statistical analysis, the four stages of fibrosis according to Metavir and Brunt were considered equivalent. Confidence interval (CI), Positive Predictive Value (PPV), Negative Predictive Value (NPV), fibrosis (F)

Biopsy stage	Sensitivity % (95% CI)	Specificity % (95% CI)	PPV% (95% CI)	NPV % (95% CI)
F≥1	83.7% (78.6-88.7)	78.2% (72.8-83.6)	92.2% (88.7-95.7)	65.6 % (59.2-72.0)
F≥2	87.5% (85-90.1)	78.4% (75.2-81.7)	69.9% (66.3-73.5)	89.5% (87.1-91.9)
F≥3	93.7% (92-95.5)	91.1% (89-93.2)	82.4% (79.9-84.9)	95.9% (94.4-97.4)
F≥4	96.2 % (94.5-97.8)	92.2% (89.9-94.6)	55.5% (51.2-59.8)	98.5% (97.4-99.5)
