Intermittent low-level vagosympathetic nerve trunk stimulation inhibits ganglionated plexi activity to prevent atrial fibrillation.

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
backgroundThe cardiac autonomic nervous system (CANS) plays a role in the occurrence and persistence of atrial fibrillation (AF). Low-level vagosympathetic nerve stimulation (LL-VNS) has been shown to inhibit the occurrence of AF.
objectiveThe novel objective of this study was to compare the effects of intermittent low- level vagosympathetic nerve stimulation (I-VNS) and continuous low-level vagosympathetic nerve stimulation (C-VNS).
methods19 beagles were randomly divided into 3 groups: Group A, rapid left atrial appendage pacing for 6 hours; Group B, rapid atrial pacing (RAP) for 6 hours and C-VNS (20 Hz, interval 0.1 ms, square wave) with 50% threshold voltage strength; Group C, RAP for 6 hours and I-VNS (continuously recurring cycles of 30-second ON, 30-second OFF). The atrial monophasic action potential (MAP) and the effective refractory periods (ERP) of the atrium and the pulmonary veins were measured at baseline, 1 hour, 3 hours and 6 hours after the experiment began. After the experiment, tyrosine hydroxylase (TH) and choline acetyl transferase (CHAT) expression levels in the anterior right ganglionated plexi (ARGP) from each group were measured.
resultsInter-group comparisons of MAP and ERP demonstrated that Group A was significantly different from Groups B and C (P < 0.05), while the difference between Groups B and C was not significant (P > 0.05). The MAP and ERP in Group A gradually decreased, reaching a minimum at 6 hours, but no significant changes were observed in Groups B and C. When compared to Group A, both Groups B and C had reduced TH and CHAT expression.
conclusionsDuring the occurrence and development of AF, I-VNS could protect the cardiovascular system, possibly replacing C-VNS. Additionally, both I-VNS and C-VNS inhibited ganglionated plexus (GP) activity during the AF prevention.
