Wiener filter unifies Hilbert and Zernike phase plates in electron microscopy.
Review in Biophysical reviews, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
We report on two key discoveries resulting from the combination of the Hilbert phase plate (HPP) and the Wiener filter: firstly, the resolution of the HPP's mixed image problem through a one-step experiment, and secondly, the unification of the Zernike phase plate (ZPP) and the HPP. When the phase of the HPP is reduced to less than π, it produces a mixed image comprising both the normal and the differential images. The HPPU (left-right unified HPP), proposed to address this issue, required a two-step experimental process. However, during our efforts to resolve the mixed image problem using either the left or right HPP, we discovered that the Wiener filtering process not only addresses this issue but also facilitates the unification of the ZPP and HPP. We will discuss the theoretical development behind these discoveries and their verification through simulations of three phase contrast methods: the Scherzer, ZPP, and HPP methods.
