Compact way to generate guide star for wavefront sensing in Bessel two-photon microscopy.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
We introduce a compact method for generating guide stars to enable direct wavefront sensing in Bessel two-photon microscopy. By sequentially modulating an axicon phase and a thin lens phase using a spatial light modulator (SLM), our approach achieves seamless switching between Bessel and Gaussian illumination beams without requiring mechanical movement or additional optical components. The Bessel beam provides an expanded field of view for imaging, while the Gaussian beam serves as a point-like guide star for wavefront sensing. Experimental validation in a Bessel two-photon light sheet microscope demonstrates that wavefront correction based on our method enhances the signal-to-noise ratio (SNR) by 7.3 times and improves axial resolution by 4.4 times.
