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.

2 · The registry

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.

Abstract

Several protocols based on repetitive transcranial magnetic stimulation (rTMS) have been proposed for treatment of a variety of neurological disorders. Despite the widespread use, little is known about the effects of rTMS on the autonomic nervous control of the cardiovascular system. Twelve volunteers underwent rTMS sessions consisted in 8-min baseline recording, 8-min 0.7-Hz rTMS stimulation at 100 % of the motor cortex excitability threshold on the prefrontal cortex of one randomly assigned hemisphere. After 8-min recovery, the same procedure was performed on the contra-lateral hemisphere. Non-invasive (Portapres device) beat-by-beat blood pressure and heart period time series were recorded and analyzed by spectral and cross-spectral analysis in the low-frequency (LF ≈ 0.1 Hz) and in the high-frequency (HF = respiratory frequency) range. Repetitive TMS, particularly after stimulation of the right hemisphere, induced a slight increase in the parasympathetic drive and no effects on the sympathetic activity. There was a significant bradycardia after stimulation on the right hemisphere, not significant bradycardia after left stimulation. LF/HF ratio was 3.8 ± 2.1 during baseline and changed to 1.9 ± 0.6 during rTMS on the left and to 1.6 ± 0.6 during rTMS on the right. No significant changes were observed in blood pressure. Low-frequency rTMS of the prefrontal cortex induces a slight parasympathetic activation and no changes in the sympathetic function.
