Peritoneal dialysis influences microRNA expression and pro-inflammatory response: results from a cross-sectional study.

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
introductionThe investigation of circulating microRNAs (miRNAs) and inflammatory response associated with the different stages of chronic kidney disease (CKD) may reveal biomarkers of disease pathogenesis. Our goal was to identifying differences in the circulating miRNAs expression between peritoneal dialysis (PD) and non-dialytic (ND) patients and determine the regulatory miRNA-target gene networks and pathways potentially involved in disease pathogenesis.
methodsThis was an exploratory cross-sectional study that included ND and PD patients with CKD stage 5 over 18 years of age. Inflammatory biomarkers and circulating miRNA expression profiles were evaluated.
resultsThe study included 20 patients (57.2 ± 11.8 years). Levels of high-sensitivity C-reactive protein [0.37 (0.07-1.40) vs. 3.90 (2.50-5.79), p = 0.038] and interleukin-6 [3.35 ± 3.08 vs. 6.82 ± 4.08, p = 0.046] were significantly lower in the ND group in comparison to the PD group, respectively. Nine miRNAs were significantly deregulated (fold change (FC) ≥ 2 and p ≤ 0.05) in the PD compared to the ND group. Computational analyses showed a large number of target genes commonly regulated by at least two of the identified miRNAs. Pathway enrichment analysis showed that G protein-coupled receptor (GPCR) signaling, insulin secretion/resistance, and energy metabolism were among significant pathways regulated by miRNA target genes.
conclusionsPatients on PD treatment showed deregulated circulating levels of the 9 identified miRNAs and higher serum inflammatory biomarkers, compared to ND patients. Genes regulated by miRNAs are mainly associated with GPCR signaling, insulin resistance, and energy metabolism, playing roles in fibrosis and inflammatory-associated functions.
