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
Existing optical phantoms often do not represent realistic optical and geometrical properties. This study aimed to fabricate a homogeneous silicone finger phantom that closely mimics the reflectance and transmittance characteristics of a human finger by precisely adjusting the absorption and reduced scattering coefficients in the visible wavelength range. The absorption and reduced scattering coefficients of a human finger were determined using a custom inverse model tailored for an integrating sphere system designed for cylindrical media illuminated along the barrel. To reproduce the retrieved optical properties in silicone, a reference database was created by characterizing the absorption spectra of 15 pigments dispersed in a silicone matrix. An automated fitting algorithm identified five suitable absorbing pigments, and their required concentrations were calculated to match the target absorption spectrum. The reduced scattering coefficient was independently controlled by varying the concentration of zirconium dioxide particles. An alginate mould was used to capture the finger geometry, ensuring anatomical accuracy of the phantom. The fabricated silicone finger phantom closely matched the human finger in both transmittance and reflectance, as well as in its anatomical shape. The Δ
