Contrast improvement in two-photon microscopy with instantaneous differential aberration imaging.
Article in Biomedical optics express, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Two-photon microscopy (TPM) has been widely used for thick tissue imaging. However, its penetration depth is fundamentally limited by the loss of signal contrast. Differential aberration imaging (DAI) can reject out-of-focus fluorescence in TPM by subtracting an aberrated image from an unaberrated one. This technique is simple and effective but compromises imaging speed because two images must be taken sequentially. Here we report a new strategy for two-photon DAI based on near-instantaneous temporal multiplexing, enabling high-speed imaging with pixel rates limited only by fluorescence lifetime and laser repetition rate. Our technique can be implemented with standard two-photon microscopes since it does not require active optical elements and it is based on a synchronized sampling strategy that does not require specialized hardware. We demonstrate and characterize the resultant contrast improvement when imaging fluorescently-labeled mouse brain at video-rate.
