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

Heavy metal bioaccumulation in marine organisms is a critical concern for the oceanic environment and food safety. Scallops, as filter-feeding bivalves, accumulate cadmium (Cd) in their midgut gland to toxic concentrations that may pose risks to human health. Despite extensive research on Cd bioaccumulation in the Yesso scallop Mizuhopecten yessoensis, a major Cd-binding protein has not yet been functionally characterized. In this study, we used high-performance liquid chromatography coupled with inductively coupled plasma mass spectrometry (HPLC-ICP-MS) to isolate Cd-binding proteins, and identified myCRP, a novel high-molecular-weight Cd-binding protein. myCRP contains a cysteine-rich sequence, resembling metallothionein Cd-binding motifs, and is expressed exclusively in the midgut gland. Cd-binding assays demonstrated that myCRP binds Cd in a dose-dependent manner. Immunostaining revealed the presence of a small cluster of myCRP-containing cells in the connective tissue surrounding digestive tubules in the midgut gland. Synchrotron radiation X-ray fluorescence (SR-XRF) analyses showed the distribution of Cd throughout the entire midgut gland tissue. We conclude that myCRP is partly responsible for Cd binding in the midgut gland. Our findings clarify a new mechanism of Cd-binding in marine organisms from both biological and molecular perspectives.
