Supertemporal Resolution Imaging of Membrane Potential via Stroboscopic Microscopy.
Article in Chemical & biomedical imaging, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Membrane potential and its fluctuation are fundamental biophysical phenomena essential to cellular activities and functions. Compared to traditional electrode-based techniques, the optical recording via developed genetically encoded voltage indicators (GEVIs) offers a combination of noninvasiveness, high spatial resolution, and increased measurement throughput. However, its application is limited by the insufficient acquisition rate and time accuracy of the camera. Here we design and apply a stroboscopic illumination scheme to boost the temporal resolution of voltage imaging, while simultaneously eliminating the artifacts caused by nonsynchronized exposure in the rolling-shutter mode. We demonstrate that commonly used GEVIs are compatible with stroboscopic voltage imaging (SVI), and our SVI scheme offers a 5-fold faster acquisition frame rate than that of conventional continuous illumination. The GEVIs tested maintain high sensitivities in the SVI mode, supporting faithful reports of intracellular depolarization waveform and intercellular gap junction-mediated depolarization coupling in human embryonic kidney 293T (HEK 293T) cell populations. SVI allows resolving the action potential (AP) waveform with less distortion and mapping action potential initiation and propagation dynamics in cultured neurons in kilohertz, beyond the restriction from the camera in the field of view.
