Tetrahedral serial multiview microscopy and image fusion for improved resolution and extent in stained zebrafish embryos.
Article in Developmental dynamics : an official publication of the American Association of Anatomists, 2024. 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
backgroundSpatial mapping on the single-cell level over the whole organism can uncover roles of molecular players involved in vertebrate development. Custom microscopes have been developed that use multiple objectives to view a sample from multiple views at the same time. Such multiview imaging approaches can improve resolution and uniformity of image quality as well as allow whole embryos to be imaged (Swoger et al., Opt Express, 2007;15(13):8029). However, multiview imaging is highly restricted to specialized equipment requiring multiple objectives or sample rotation with automated hardware.
resultsOur approach uses a standard single-objective confocal microscope to perform serial multiview imaging. Multiple views are imaged sequentially by mounting the fixed sample in an agarose tetrahedron that is manually rotated in between imaging each face. Computational image fusion allows for a joint 3D image to be created from multiple tiled Z-stacks acquired from different angles. The resulting fused image has improved resolution and imaging extent.
conclusionWith this technique, multiview imaging can be performed on a variety of common single-objective microscopes to allow for whole-embryo, high-resolution imaging.
