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
Bacillus thuringiensis (Bt) is a widely used microbial insecticide, but its effectiveness is limited due to the degradation of Bt spores and crystals under UV radiation from sunlight. The objective of this study was to develop a novel Bt formulation with improved UV protection by utilizing sulfur quantum dots (SQDs) as stabilizing agents in a Pickering emulsion. The SQDs were comprehensively characterized using FTIR, XRD, TEM, HRTEM, UV, and fluorescence analyses, which confirmed the formation of well-dispersed, spherical SQDs. The microcapsule formulation with SQDs demonstrated superior UV stability, as it maintained 57.77% spore viability after 96 h of UV exposure, in comparison to 33.74% and 31.25% for the SQDs formulation (non-microcapsules) and unprotected Bt formulations (free spore, as a control), respectively. Furthermore, the microcapsule formulation exhibited higher insecticidal activity, resulting in a larval mortality of 71.22%, as opposed to 42.34% and 38.42% for the other formulations. These findings emphasize the effectiveness of microcapsule formulation with SQDs in safeguarding Bt spores and crystals against UV radiation, thereby enhancing their practical application in pest control. This approach presents a promising strategy for the development of biopesticides that are more resilient and have a longer shelf life.
