The near-infrared bacteriophytochrome-derived fluorescent protein PENELOPE enables RESOLFT superresolution microscopy.

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
REversible Saturable Optical Linear Fluorescence Transitions (RESOLFT) superresolution microscopy fundamentally overcomes the diffraction barrier in far-field fluorescence microscopy. It relies on reversibly switchable fluorescent proteins (RSFPs) that allow repeated light-induced transitions between fluorescent on- and nonfluorescent off-states. Because these transitions are induced by low-light intensities, RESOLFT superresolution microscopy is particularly suitable for live-cell imaging. So far, RESOLFT imaging has only been performed in the visible range of the electromagnetic spectrum. To expand the RESOLFT concept into the near-infrared (NIR) region, which is characterized by reduced autofluorescence, lower scattering and decreased phototoxicity, we developed the
