Scattering reduced imaging of spheroids via refractive index estimation and shift-variant deconvolution.
Article in Biomedical optics express, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Confocal laser scanning microscopy (CLSM) is widely used in biological research, but imaging the deep regions of three-dimensional samples like spheroids is challenging due to scattering. We propose a computational method that estimates the refractive index distribution from CLSM images, calculates position-dependent point-spread functions (PSFs) using a multi-diffraction propagation model for both excitation and emission light, and applies shift-variant deconvolution. This approach enables the resolution of deep spheroid structures that could not be resolved in conventional CLSM images. It requires no hardware modifications to conventional CLSM systems, enabling high-quality three-dimensional imaging of scattering samples using conventional equipment.
