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
The analysis of possible allergens, impurities, and contaminants in perfumes and the determination of their volatile fingerprints are of high importance in determining their quality. At the same time, the analysis of perfumes with a significant water content can require complex procedures or large amounts of material. These new products are becoming increasingly popular as they reduce skin dryness and irritation, but they require the addition of additives to improve the solubility of all fragrance components. Direct injection into gas chromatography can lead to interferences and requires more frequent maintenance of the chromatographic system, while traditional extraction methods need several steps, a large volume of sample and material, and the use of toxic solvents. In this study, pipette-tip micro-solid-phase extraction (PT-µSPE) was used and optimized as an innovative, simple, sustainable, and time-saving approach. It requires only 10 mg Celite and 10 mg sample while elution is carried out with 100 mg heptane/ethyl acetate (70/30, p/p). The extraction is coupled with GC analysis with simultaneous FID and MS detection (GC-MS/FID), which is used for qualitative, semi-quantitative, and quantitative purposes. The performance of the PT-µSPE method was validated and successfully applied to commercial samples. In addition, the performance of the developed method and of the reference approaches was evaluated, focusing mainly on the overall impact of analysis in accordance with the principles of White Analytical Chemistry. The results show that the PT-µSPE method is more balanced than the conventional methods in terms of analytical performance, greenness, and practical efficiency, making it a valuable alternative for routine use in the fragrance industry.
