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
5-Hydroxymethylfurfural (HMF), a product of the Maillard reaction and caramelization in honey, serves as a crucial marker of food quality and thermal processing, underscoring the importance of regulatory surveillance for consumer safety. This study introduces a method for rapid, high throughput and eco-friendly detection of HMF, using derivatization in matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS). 5,10,15,20-Tetrakis-(4-aminophenyl)-porphyrin was employed for in-situ derivatization of aldehydes after extraction by ethyl acetate, enhancing detection sensitivity by shifting low-molecular-weight aldehydes to higher regions. The calibration curves for HMF determination exhibited outstanding linearity. The detection limit reached 0.347 mg/kg with good accuracy and precision. Variations in the content of HMF in honey during heating were also assessed, revealing the increased formation of HMF under high temperature and prolonged heating. The method's proficiency was evidenced through the detection of various aldehydes. This method represents an advance in rapid analysis for food safety, aligning with green chemistry principles.
