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
The treatment of chronic disease (CKD) is a great challenge in healthcare that requires an innovative approach to address its complex nature. RNA nanotechnology has emerged rapidly and received attention in the last few years because of its significant aptitude for therapies. Hence, the present study aimed to design, construct, and characterize a multifunctional (anti-miR-34a DNA aptamer-kidney targeted) RNA nanoparticle (RNPs) based on bacteriophage phi29 packaging RNA three-way junction (pRNA-3WJ), and then explore their in vivo toxicity and therapeutic potentials in mice model of CKD. After confirming the safety and specific targeting capability of the prepared core 3WJ (3WJ) and the therapeutic 3WJ (3WJ-Kapt/anti-miR-34a) RNPs to renal tissue using healthy mice, CKD was induced in C57BL/6 mice using adenine. CKD mice were treated with a single intravenous injection of 3WJ or 3WJ-Kapt/anti-miR-34a. Every week, 5 mice of each group were selected randomly for sample collection for 4 weeks post-treatment. The anti-miR-34a 3WJ-RNPs have shown stability, safety, and efficacy in renal targeting using DNA aptamer, by targeting miR-34a in renal tissue, 3WJ-Kapt/anti-miR-34a suppressed profibrotic gene expression and induced anti-fibrotic pathways' expression. Our present study provides preliminary and pioneering evidence for the promising treatment of renal fibrosis and CKD through targeting miR-34a in the renal tissue by 3WJ-RNPs. The CKD mice showed marked time-dependent up-regulation of the renal profibrotic pathways, including TGF-β, FGF2, and WNT/β-catenin pathways. The same mice showed suppressed renal expression of the antifibrotic pathways, including α and β Klotho, SMAD7, and SIRT1. The prepared anti-miR-34a 3WJ-RNPs have shown stability, safety, and efficacy in renal targeting using DNA aptamer. By targeting miR-34a in renal tissue, 3WJ-Kapt/anti-miR-34a suppressed profibrotic gene expression and induced anti-fibrotic pathways' expression. Our present study provides preliminary and pioneer evidence for the promising treatment of renal fibrosis and CKD through targeting miR-34a in the renal tissue by 3WJ-RNPs.
