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

Mouse models are valuable for studying the systemic effects of arrhythmia, but traditional methods of heart pacing are invasive and technically complex. Cardiac optogenetics enables precise control of cardiac activity using light-sensitive ion channels and has been used for tachypacing, resynchronization, and defibrillation in animal models. Recent advances in opsins with red-shifted activation spectra and optimized light delivery strategies have enhanced noninvasive pacing approaches, particularly in mammalian models. Here, we use an area illumination approach for light stimulation through the intact chest to perform in vivo, noninvasive optogenetic tachypacing in transgenic mice expressing ReaChR with low irradiance (<1 mW/mm
