MicroRNAs as potential biomarkers for the diagnosis of glioma: A systematic review and meta‐analysis
Open accessAbstract
Glioma is the most common central nervous system tumor and associated with poor prognosis. Identifying effective diagnostic biomarkers for glioma is particularly important in order to guide optimizing treatment. MicroRNAs (miRNAs) have drawn much attention because of their diagnostic value in diverse cancers, including glioma. We summarized studies to identify the potential diagnostic values of miRNAs in glioma patients. We included articles reporting miRNAs for differentiation of glioma patients from controls. We calculated sensitivities, specificities, and area under the curves (AUC) of individual miRNA and miRNA panels. We found that overall sensitivity, specificity, and AUC of miRNAs in diagnosis of glioma were 85% (95% confidence interval [CI]: 0.81‐0.89), 90% (95% CI 0.85‐0.93), and 93% (95% CI 0.91‐0.95), respectively. Meta‐regression analysis showed that the detection of miRNAs expression in cerebrospinal fluid (CSF) and brain tissue largely improved the diagnostic accuracy. Likewise, panels of multiple miRNAs could enhance the pooled sensitivity. Moreover, AUC of miR‐21 was 0.88, with 86% sensitivity and 94% specificity. This study demonstrated that miRNAs could function as potential diagnosis markers in glioma. Detection of miRNAs in CSF and brain tissue displays high accuracy in the diagnosis of glioma.

A meta-analysis of nine studies revealed that high miR-21 expression is associated with a poor prognosis in glioma patients.
“A meta-analysis of nine studies revealed that high miR-21 expression is associated with a poor prognosis in glioma patients [34], [35].”

The Results (Study characteristics; page unavailable) say the paper’s miR-21 meta-analysis included four studies, not nine. The Results (Diagnosis; page unavailable) report diagnostic accuracy, not an association between high miR-21 expression and poor prognosis. (LLM, conf=0.88)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
