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
Colorectal cancer (CRC) is one of the most prevalent malignant diseases worldwide. Recurrence is associated with the poor survival of patients with CRC. Targeted therapy and precision medicine for recurrent CRC may improve the clinical outcome. Therefore, finding biomarkers that can detect CRC early, assess its prognosis and survival, and predict its treatment response is key to improving the clinical prognosis. The aim of this study was to assess CRC recurrence by analyzing molecular differences using postoperative specimens. Whole-exome sequencing was first used to evaluate the molecular differences in CRC tissues from patients with recurrent disease, and the results were then verified with tissue array methods. The regulation of single nucleotide polymorphisms (SNPs) in long noncoding regions of interest was analyzed in the presence of target microRNAs (miRs) using luciferase assays. The results demonstrated that in patients with recurrent CRC, the G allele was mainly detected at the rs28382740 SNP in the 3'-untranslated region of the X-linked inhibitor of apoptosis (XIAP)-encoding gene. From the tissue arrays, 60% (3/5) of patients with the G allele of the rs28382740 SNP were diagnosed with CRC recurrence, whilst only 10% (1/10) of patients without the G allele had recurrent CRC (P=0.077). Furthermore, XIAP levels were high in non-CRC (50%; 2/4) and CRC (75%; 3/4) tissues of patients with recurrent disease and CRC (54.5%; 6/11) tissues of patients without recurrent disease. However, but only 9.1% (1/11) of non-CRC tissues of nonrecurrent patients had significantly high XIAP expression levels (P=0.022). Using a luciferase assay, it was demonstrated that miR-24s (miR-24-1-5p and miR-24-2-5p) targeting the rs28382740 SNP reduced XIAP levels in CRC cells with rs28382740 SNP genotype G. These results indicate that apoptosis-related proteins, such as XIAP, may be therapeutic targets or biomarkers for tumor development. The data from the present study support an inhibitory effect of miR-24s on XIAP expression. However, this inhibitory potency depends on the rs28382740 SNP genotype and may alleviate CRC progression by regulating the expression of XIAP.
