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
backgroundColorectal cancer (CRC), a complex and multifactorial disease, has been associated with elevated expression of microRNA miR-182-5p, although its precise regulatory role in CRC progression remains unclear. This study aims to identify potential therapeutic targets to improve clinical outcomes and to decipher the intricate role of miR-182-5p in the pathobiology of CRC.
methodsWe conducted comprehensive bioinformatics analyses using GEO databases to investigate differences in miRNA expression between CRC and normal tissues, with a particular focus on miR-182-5p. Its expression levels in CRC cells and tumor tissues were quantified by quantitative real-time PCR (qRT-PCR). The expression of neurocalcin delta (NCALD) and proteins related to Wnt/β-catenin signalling was evaluated by qRT-PCR and Western blotting. Pathological changes in tumor-bearing mice as well as the proliferation, invasion, and migration of CRC cells, were assessed. Tumor cell proliferation and apoptosis were examined using Ki-67 immunohistochemistry and TUNEL staining, respectively. A dual luciferase reporter assay explored the regulatory interaction between miR-182-5p and NCALD.
resultsOur findings reveal significantly elevated miR-182-5p levels in CRC tissues and cell lines, positively correlated with tumor invasion depth, differentiation degree, clinical stage, and lymph node metastasis. miR-182-5p appears to accelerate CRC progression in both cell lines and mouse models by downregulating NCALD, thereby enhancing Wnt/β-catenin signalling. This study identifies miR-182-5p as a pivotal enhancer of CRC progression, modulating Wnt/β-catenin signalling via NCALD regulation.
conclusionsThe findings position the miR-182-5p/NCALD axis as promising targets for CRC therapy, offering new avenues for treatment strategies.
