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
Light-irradiation-based color-conversion displays are considered an emerging technology with considerable potential because they are easy to fabricate; however, color precision is limited by inefficient heating and uneven temperature distribution, and pattern extinction is delayed by poor heat dissipation. This study proposes a light-irradiation-based color-conversion display that can produce full color from a near-infrared (NIR) laser using carbon nanotubes (CNTs) with efficient photothermal conversion and heat-diffusion functions. Light-irradiation-based color-conversion displays have a more straightforward structure than conventional electronic-circuit-based displays. The proposed design uses an NIR laser as the driving energy source, which makes it highly efficient. In addition, a color-conversion layer based on a thermochromic liquid crystal (TLC) changes the color to red, green, or blue depending on the temperature, and a CNT-based thermal property control layer, which reacts to NIR photothermally, is used to achieve immediate thermal control. These layers can be applied to a flexible substrate to maintain stable performance, even under bending or deformation. Precisely controlling the laser power can help achieve a subtle temperature change of 27-32 °C and generate a corresponding color change in a specific area of the TLC-based color-conversion layer. Considering rapid and reversible color conversion is achievable by turning the NIR laser on and off, this method is suitable for various applications, such as high-speed responsive displays, smart sensors, and customizable visual information systems.
