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.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Temporal interference stimulation (TIS) is a promising noninvasive method for neurostimulation, yet its mechanism remains debated. TIS is often described as delivering low-frequency stimulation via the amplitude modulation (beat frequency) of interfering kHz carriers. However, this view overlooks known biophysical responses to kHz stimuli. Here, we test modulated (TIS) and unmodulated kHz waveforms on peripheral nerves in Locusta migratoria and in human sensory and motor pathways. We find that stimulation thresholds and strength-frequency relationships are governed by the kHz carrier itself, with minimal dependence on amplitude modulation. Across 0.5-12.5 kHz in humans and up to 100 kHz in locusts, all waveforms show overlapping excitation behavior, indicating a shared underlying mechanism. Our results support the hypothesis that suprathreshold TIS acts through kHz rectification, rather than envelope-specific effects. We further explore modulation frequency resonance, tonic vs. phasic effects, and suggest that two-electrode premodulated kHz may offer advantages over multielectrode TIS approaches.
