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
Food adulteration and species mislabeling represent important challenges for food safety, regulatory control, and consumer protection, particularly for products requiring species-specific authentication. This study investigated two complementary analytical approaches relevant to meat authentication: species-specific real-time polymerase chain reaction (real-time PCR) for the molecular detection of porcine mitochondrial deoxyribonucleic acid (DNA) and Fourier-transform near-infrared (FT-NIR) spectroscopy combined with chemometric analysis for exploratory assessment of slaughter-related compositional changes in a controlled murine proof-of-concept model. A total of 85 commercially available Halal-labeled meat products, including sausages, cutlets, minced meat, dumplings, raw meat, and seasoning products, were analyzed for the presence of porcine mitochondrial DNA. Under the applied qualitative assay conditions, porcine mitochondrial DNA was detected in 64 of 85 analyzed samples (75.3%). This finding is specific to the investigated sample set and does not distinguish intentional formulation or substitution from unintended cross-contact or other potential sources of porcine-derived DNA. In parallel, FT-NIR spectroscopy over the 10,000-4000 cm
