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
backgroundChronic kidney disease (CKD) is an independent cardiovascular risk factor. Patients with CKD develop uremic cardiomyopathy characterized by activation of the sympathetic nervous system, left ventricular hypertrophy, and accumulation of uremic toxins such as indoxyl sulfate (IS). The aim of this study was to assess the effects of renal denervation (RDN) on uremic cardiomyopathy in a rat model of CKD.
methodsSprague-Dawley rats were fed a standard chow (control group, n=6) or a 0.25% adenine-enriched chow (n=16) for 16 weeks to induce CKD. After 4 weeks, CKD rats with CKD were subjected to bilateral RDN (AD-RDN, n=8) or to sham operation (AD, n=8). Blood pressure measurements, echocardiography, and cardiac magnetic resonance imaging were deployed during the experiment. Left ventricular hypertrophy was evaluated histologically. IS was measured using ELISA. In H9C2 cardiomyoblasts, the hypertrophic effects of IS were characterized in vitro.
resultsIn AD rats, left ventricular septal wall thickness (2.37±0.036 versus 1.91±0.014 mm in CTRL,
conclusionsIn a rat model of CKD, improved cardiac function following RDN was associated with reduced plasma concentrations of IS. To the present, IS remains a persistent clinical concern in patients with CKD due to its inefficient removal by conventional hemodialysis and its significant role in promoting both kidney and myocardial disease. Thus, RDN may ameliorate uremic cardiomyopathy by reducing IS and potentially represents a treatment option for patients with CKD and cardiovascular disease. Clinical trials are warranted to investigate the effects of RDN on cardiovascular outcomes in patients with CKD.
