High expression of microRNA-199a-5p is associated with superior clinical outcomes in patients with locally advanced rectal cancer.

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
purposeWe aimed to identify biomarkers of response to preoperative CRT in patients with LARC using comprehensive miRNA analysis.
methodsThis study included 65 rectal cancer specimens and 89 serum samples from patients diagnosed with LARC and treated with preoperative. All specimens were collected before CRT for evaluation of biologic differences between the good and poor CRT response groups (ypStage 0/I versus II/III/IV). For specific miRNA discovery, 800 miRNAs in 20 rectal cancer specimens were analyzed with a NanoString assay. For validation, a total of 65 tissue and 89 serum samples were tested with reverse transcription-polymerase chain reaction (RT-PCR).
resultsIn the discovery set, 16 target miRNAs were detected. In the validation set, higher expression of three miRNAs (miR-199a/b-3p, miR-199a-5p, and miR-199b-5p) was significantly associated with better response to CRT. In the univariate survival analysis, upregulation of these three miRNAs was associated with superior relapse-free survival (RFS) and overall survival (OS). Meanwhile, only a higher level of tissue miR-199a-5p was associated with superior RFS [hazard ratio (HR), 0.0.91; 95% confidence interval (CI) 0.035-0.580; p = 0.002] and OS (HR, 0.272; 95% CI 0.023-0.658; p < 0.001) in the multivariate survival analysis. Also, a higher level of exosomal miR-199b-5p correlated with better response to CRT (p = 0.0397).
conclusionHigh expression of tissue miR-199a/b-3p, miR-199a-5p, and miR-199b-5p was significantly associated with response to CRT, and a high level of tissue miR-199a-5p was associated with superior survival outcomes. Also, upregulated exosomal miR-199b-5p correlated with CRT response, reflecting its promise as a circulating biomarker of CRT response in patients with LARC.
