1 · What the graph read from it

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.

Abstract

Low-level transcutaneous vagus nerve stimulation at the tragus (LLTS) is anti-adrenergic. We aimed to evaluate the acute effects of LLTS on left ventricular (LV) function and autonomic tone. Patients with diastolic dysfunction and preserved LV ejection fraction were enrolled in a prospective, randomized, double-blind, 2 × 2 cross-over study. Patients received two separate, 1-h sessions, at least 1 day apart, of active LLTS (20 Hz, 1 mA below the discomfort threshold) and sham stimulation. Echocardiography was performed after LLTS or sham stimulation to assess cardiac function. A 5-min ECG was performed to assess heart rate variability (HRV). Twenty-four patients were enrolled. LV global longitudinal strain improved by 1.8 ± 0.9% during active LLTS compared to sham stimulation (p = 0.001). Relative to baseline, HRV frequency domain components (low frequency, high frequency, and their ratio) were favorably altered after LLTS compared to sham stimulation (all p < 0.05). We concluded that LLTS acutely ameliorates cardiac mechanics by modulating the autonomic tone. Trial registration: NCT02983448.
