{Abstract}: <B>OBJECTIVE: </B>With the global increase in chronic liver disease and cirrhosis, there is an increasing need to identify non-invasive biomarkers to measure the severity of disease progression while reducing reliance on pathological biopsies. This study aimed to comprehensively evaluate the diagnostic value of PRO-C3 as a biomarker for staging liver fibrosis in patients with viral hepatitis or fatty liver disease.<BR><B>METHODS: </B>Articles published until January 6, 2023, were searched in the PubMed, Embase, MEDLINE, Web of Science, and Cochrane Library databases. The Quality Assessment of Diagnostic Accuracy Studies-2 tool was used to evaluate the quality of the included studies. Pooled sensitivity, specificity, diagnostic odds ratio, and likelihood ratios were integrated using a random-effects model, and a summary receiver operating characteristic curve was constructed. Publication bias was also detected. Subgroup and meta-regression analyses, as well as sensitivity analysis, were also performed.<BR><B>RESULTS: </B>Fourteen studies with 4315 patients were included. Summary area under the curve of PRO-C3 for the identification of significant fibrosis (≥ F2) and advanced fibrosis (≥ F3) was 0.80 (95% confidence interval: 0.76-0.83). Subgroup and meta-regression analyses suggested that disease type and sample size may be the primary factors of heterogeneity in PRO-C3 diagnosis of ≥ F2, while study design, study sample type, and enzyme-linked immunosorbent assay kit brand may be the primary sources of heterogeneity in PRO-C3 diagnosis of ≥ F3.<BR><B>CONCLUSIONS: </B>PRO-C3 demonstrated clinically meaningful diagnostic accuracy when used alone as a non-invasive biomarker for diagnosing the liver fibrosis stage in individuals with viral hepatitis or fatty liver disease.
