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
Fatty acids (FAs) are biochemical components of food, essential for human health due to their numerous biological functions. However, many of then if consumed in excess can trigger disfunctions/illness. Therefore, analytical methods, such as gas chromatography (GC-FID) are essential for the accurate identification and quantification of FAs, playing an important role in food safety and quality assessment. The aim of this study was to compare two FAs extraction protocols and to adapt, optimize, and validate a new one for food FAs extraction, considering the principles of green chemistry (sustainability and environmentally friendly). The research included four main steps: (A) comparison of two FAs extraction protocols for Gas Chromatography Flame Ionization Detector (GC-FID) analysis; (B) adaptation and optimization of four new extraction protocols; (C) verification of the most promising protocol; and (D) evaluation of the greenness profile. Comparatively, the PE2 protocol detected a greater diversity of FAs and a wider range of medium/long chain saturated fatty acids (SFA), but with divergences from values declared on food labels, mainly in the quantification of unsaturated fatty acids (UFA), unlike PE1, which presented lipid fraction values closer to nutritional information and greater extraction of short/medium chain FAs. The improved protocol, PE6, proved to be more efficient in extracting short, medium, and long chain FAs, as well as having SFA and UFA values closer to nutritional values in different food matrices. Furthermore, PE6 also showed improvements in relation to green chemistry aspects, presenting a higher greenness profile score, which indicates that it is more sustainable and generates less environmental impact. These results underscore the importance and relevance of continuing to develop analytical methods for food that are both effective and environmentally responsible.
