Association of B-cell lymphoma 2/microRNA-497 gene expression ratio score with metastasis in patients with colorectal cancer: A propensity-matched cohort analysis.
Article in Journal of clinical laboratory analysis, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundDeregulated microRNAs (miRs) significantly impact cancer development and progression. Our in silico analysis revealed that miR-497 and its target gene B-cell lymphoma-2 (BCL2) could be related to poor cancer outcomes. PURPOSE: To investigate the BCL2/miRNA-497 expression ratio in colorectal cancer (CRC) and explore its association with the clinicopathological characteristics and CRC prognosis.
methodsArchived samples from 106 CRC patients were enrolled. MiR-497 and BCL2 gene expressions were detected by Taq-Man Real-Time quantitative polymerase chain reaction in propensity-matched metastatic and nonmetastatic cohorts after elimination of confounder bias.
resultsB-cell lymphoma-2 gene was upregulated in metastatic samples (median = 1.16, 95%CI = 1.09-1.60) compared to nonmetastatic (median = 1.02, 95%CI = 0.89-1.25, p < 0.001). In contrast, lower levels of miR-495 were detected in specimens with distant metastasis (median = 0.05, 95%CI = 0.04-0.20) than nonmetastatic samples (median = 0.54, 95%CI = 0.47-0.58, p < 0.001). Estimated BCL2/miR-497 ratio yielded a significant differential expression between the two cohort groups. Higher scores were observed in metastasis group (median = 1.39, 95%CI = 0.9-1.51) than nonmetastatic patients (median = 0.29, 95%CI = 0.19-0.39, p < 0.001). Receiver operating characteristic curve analysis showed BCL2/miR-497 ratio score to have the highest predictive accuracy for metastasis at presentation. The area under the curve was 0.90 (95%CI = 0.839-0.964, p < 0.001) at cut-off of >0.525, with high sensitivity 81.1% (95%CI = 68.6%-89.4%) and specificity 92.5% (95%CI = 82.1%-97.0%). Also, the ratio score was negatively correlated with disease-free survival (r = -0.676, p < 0.001) and overall survival times (r = -0.650, p < 0.001). Kaplan-Meier curves showed lower survival rates in cohorts with high-score compared to low-score patients.
conclusionThe BCL2/miR497 expression ratio is associated with poor CRC prognosis in terms of metastasis and short survival.
