Effects of Syringaldehyde/Gum Arabic Composite Chitosan Thermochromic Microcapsules on the Coating Properties of Basswood Surface.

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
Thermochromic wood coatings hold promising application prospects, yet conventional thermochromic microcapsules are limited by monotonous color transitions and non-environmentally friendly wall materials. In this study, two formaldehyde-free thermochromic microcapsules were prepared via spray drying using crystal violet lactone (CVL) and bisphenol A (BPA) as the core system, with chitosan-syringaldehyde (SA-MCs, decyl alcohol as solvent, Schiff base crosslinking) and chitosan-gum Arabic (GA-MCs, lauryl alcohol as solvent, electrostatic complex coacervation) as the wall materials, respectively. These microcapsules were incorporated into basswood ultraviolet (UV) coatings at mass fractions of 1%, 3%, 5%, 7%, and 9%. With increasing microcapsule content, the gloss of both coatings decreased progressively, roughness increased gradually, and the color-changing amplitude, expressed as the color difference (Δ
