Palytoxin Signal in LC-MS and UV: Preliminary Investigation on the Effect of Solvent and Temperature.
Article in Toxins, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Palytoxins (PLTXs) and ovatoxins (OVTXs) are a group of highly potent marine toxins that pose significant health risks through seafood contamination and environmental exposure. OVTX-producing algae have been linked to dermatitis and respiratory distress in Mediterranean beachgoers, while serious public health concerns are related to PLTX accumulation in seafood. In 2009, the European Food Safety Authority highlighted the need for analytical detection methods of the PLTX group of toxins and for the preparation of reference materials. This study investigates the stability of the palytoxin signal using liquid chromatography tandem mass spectrometry (LC-MRM-MS) and UV-Vis spectrophotometry under different experimental conditions: three concentrations (10, 1, and 0.5 µg/mL), three methanol-water mixtures (10%, 50%, and 90%), and two temperatures (6 °C and 25 °C). The results showed that the PLTX signal response is significantly influenced by the experimental conditions used. LC-MRM-MS analysis revealed the optimal response of PLTX in 50% and 90% MeOH at 25 °C, with minimal signal loss occurring over 16 h (9% and 6%). UV-Vis data indicated reduced absorbance in 10% MeOH, but a stable spectral intensity over 21 h in all the tested solvent mixtures. These results underscore the necessity of carefully controlled experimental conditions to ensure accurate and reproducible PLTX detection in environmental and food safety monitoring.
