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
backgroundOveractivity of the hepatic and renal sympathetic nerves is associated with chronic cardiovascular and metabolic conditions, including hypertension.
aimsWe studied the effect of combined renal and hepatic denervation through treatment of the common hepatic artery and the renal arteries.
methodsDenervation was performed in the common hepatic artery and both renal arteries and their major branch vessels in normotensive swine using the same multielectrode radiofrequency (RF) ablation catheter (Symplicity Spyral). Renal and liver tissue samples were obtained for histological examination in two cohorts at 7 and 28 days post-procedure (n=5 sham, n=10 denervation for each timepoint).
resultsCombined hepatic and renal denervation was successfully achieved in all animals. At 7 days, the mean lesion depth was 5.8±1.4 mm in the renal arteries and 4.7±0.7 mm in the hepatic artery. Compared with controls, the mean renal cortical norepinephrine (NE) levels were reduced by 88.2% in the 7-day model and by 84.5% in the 28-day model. Liver NE decreased by 94.6% at 7 days and by 91.1% at 28 days (p<0.0001 for all comparisons with baseline). No inadvertent injury was detected in the treated arteries or adjacent tissues.
conclusionsCombined hepatic and renal denervation using the same multielectrode RF denervation system resulted in a substantial reduction in both renal and hepatic tissue NE levels that was sustained up to 28 days without collateral tissue injury. These mechanistic findings may have implications for the treatment of chronic diseases impacted by hepatic and renal sympathetic nervous system overactivity.
