Aberration-free digital holographic phase imaging using the derivative-based principal component analysis.
Article in Journal of biomedical optics, 2021. 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
significanceDigital holographic microscopy is widely used to get the quantitative phase information of transparent cells.
aimHowever, the sample phase is superimposed with aberrations. To quantify the phase information, aberrations need to be fully compensated. APPROACH: We propose a technique to obtain aberration-free phase imaging, using the derivative-based principal component analysis (dPCA).
resultsWith dPCA, almost all aberrations can be extracted and compensated without requirements on background segmentation, making it efficient and convenient.
conclusionsIt solves the problem that the conventional principal component analysis (PCA) algorithm cannot compensate the common but intricate higher order cross-term aberrations, such as astigmatism and coma. Moreover, the dPCA strategy proposed here is not only suitable for aberration compensation but also applicable for other cases where there exist cross-terms that cannot be analyzed with the PCA algorithm.
