Expression and diagnostic value of circulating miRNA-190 and miRNA-197 in patients with pulmonary thromboembolism.
Article in Journal of clinical laboratory analysis, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundDiagnosing pulmonary thromboembolism (PTE) remains challenging due to the lack of specific clinical symptoms and biomarkers. Circulating microRNAs (miRNAs) have proved to be potential biomarkers for numerous cardiovascular diseases. The aims of this study were to quantitatively analyze the expression of plasma miRNA-190 and miRNA-197 in patients with PTE and to evaluate the diagnostic value for PTE.
methodsThirty patients diagnosed with PTE by computed tomographic pulmonary angiography at the emergency department were enrolled in this study, and plasma was collected immediately. For comparison, myocardial infarction (MI, n = 45) and healthy participants (NC, n = 45) were recruited as the control groups. Quantitative reverse transcription PCR (qRT-PCR) was conducted to reveal the relative expression levels of miRNA-190 and miRNA-197 in each group. The plasma concentrations of D-dimer were measured by immunoturbidimetric assay. The diagnostic value was evaluated by analyzing the area under the receiver operating characteristic curve (AUC).
resultsThe relative expression levels of miRNA-190 and miRNA-197 in the PTE group were both significantly higher than in the MI group (t = 3.602 t = 4.791, P < .05, respectively) and the healthy control group (t = 5.814, t = 5.886, P < .05, respectively). As diagnostic indicator, the sensitivity and specificity of miRNA-190 were 75.56% and 80%, respectively, with an AUC of 0.7844 (95%CI: 0.6858-0.8831, P < .001). The sensitivity and specificity of miRNA-197 were 73.33% and 86.67%, respectively, with an AUC value of 0.7931 (95%CI: 0.6870-0.8991, P < .001). Combining miRNA-190 and miRNA-197 with D-dimer levels significantly increased the diagnostic power, improving the AUC to 0.9536 (95% CI: 0.9083-0.9989, P < .001).
conclusionsThe relative expression levels of miRNA-190 and miRNA-197 in PTE patients were significantly higher than in the MI and healthy control groups, indicating that (a) both may be involved in the pathophysiological process of PTE and (b) both may serve as potential noninvasive diagnostic markers for PTE. The combination of miRNA-190, miRNA-197, and D-dimer levels showed better sensitivity and specificity, which is more conducive to the diagnosis of PTE.
