1 · What the graph read from it

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.

2 · The registry

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 common octopus (Octopus vulgaris) is a highly valued seafood species, whose flavour and palatability are often linked to its geographic origin. However, globalized supply chains have increased the risk of mislabelling. Lipid metabolism in marine organisms is shaped by environmental conditions, then lipidomics offers a promising tool for origin authentication. This study used HILIC-LC-MS&MS/MS to profile the polar lipidome of O. vulgaris arm muscle from three Iberian Atlantic landing sites: Ría de Arousa (Spain), Peniche, and Santa Luzia (Portugal). While total lipid content was consistent across sites, Peniche samples showed lower phospholipid levels, and Santa Luzia samples showed elevated LPE/PE and LPC/PC ratios, possibly reflecting stress or degradation. Ether-linked phospholipids and the sphingolipid CAEP were most abundant in Ría de Arousa, contributing to site discrimination. These findings demonstrate the potential of lipidomic profiling as a tool for seafood traceability, offering insights into environmental and dietary influences on lipid composition.
