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

This study investigated the impacts of pre-rigor ultrasonication (0, US300, and US600 W for 30 min with the frequency of 20 kHz) on pH variation and quality attributes of beef muscle, along with the underlying mechanisms related to glycolytic and mitochondrial metabolism at the early postmortem. Results demonstrated that both pre-rigor US treatments, particularly US600, accelerated early postmortem pH decline as well as improved meat color redness, water-holding capacity, and tenderness during subsequent aging. Mechanistically, US600 potentiated pH decline through dual pathways involving direct upregulation of sarcoplasmic calcium and glycolytic enzyme activities, coupled with the disruption of mitochondrial structure and function. However, US300 accelerated glycolytic flux and pH decline only through regulating mitochondrial metabolism without directly affecting glycolytic enzyme activities. Moreover, the reasons for the improved beef quality were integrated from both pH-dependent and independent pathways. This work elucidated how postmortem energy metabolism and the resulting beef quality responded to the variations in pre-rigor US, informing the rational design of potential US technology for consistent high-quality beef production.
