Respiratory Sinus Arrhythmia Attenuation via Targeted Lung Denervation in Sheep and Humans.

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
backgroundTargeted lung denervation (TLD) is a novel bronchoscopic therapy that disrupts parasympathetic pulmonary nerve input to the lung. Parasympathetic input to the heart originating from the lungs contributes to respiratory sinus arrhythmia (RSA) and disruption of pulmonary nerves via TLD may impact RSA.
objectiveThe aim of this study was to assess the potential of TLD to affect RSA in sheep and humans.
methodsTLD was performed in 5 sheep and 9 humans using a novel lung denervation system (Nu-vaira Inc., Minneapolis, MN, USA) with an electrocardiogram collected before and after the procedure. Frequency domain analysis of heart rate variability was performed in 5 sheep and 6 humans with presence of RSA approximated as high-frequency power (HF power).
resultsHF power decreased in 3 of 5 sheep with 1 animal reaching less than 7% of its baseline HF power 30 days after TLD. The average treatment location was more distal in the remaining 2 animals, which did not exhibit RSA attenuation, suggesting diminished denervation. HF power decreased in 5 of 6 humans, with 3 subjects reaching less than 50% of their baseline HF power 90 days after TLD.
conclusionsTLD appeared to attenuate RSA in both sheep and human cohorts of this sub-study. Further confirmation in humans is necessary to allow for RSA attenuation to be used as a marker of successful lung denervation via TLD.
