Image Reconstruction with Maclaurin Series Expansion.
Article in International journal of biomedical research & practice, 2025. 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
This is a forward-thinking theoretical investigation and may not have practical values for current imaging systems. This investigation assumes that there is no noise in the measurements, the signals are continuous (not sampled), the computer has perfect precession, and there are no round-off errors. Under these unrealistic conditions, we can form a Maclaurin series expansion in the Fourier domain with measurements in a small scanning angular range. We show that this Maclaurin series expansion converges in the entire Fourier space. As a result, a complete data set is available for image reconstruction. The Fourier domain is complex; the expansion coefficients are most likely complex with real parts and imaginary parts. Computer simulations are performed to illustrate a 2D spatial-domain image can be obtained if a Fourier-domain truncated Maclaurin series expansion is available. Our goal is to use minimum data for trust-worthy reconstruction without any prior knowledge and training data.
