Blood cadmium and mortality among U.S. stroke survivors: a survey-weighted NHANES-linked cohort study of competing risks and renal pathways

Paper C Not peer reviewed Observational

Key takeaways

This study looked at cadmium levels in the blood of U.S. stroke survivors and whether higher levels went with a higher risk of dying. Cadmium is a toxic metal that people take in mostly from cigarette smoke and some foods, and the kidneys hold onto it. The researchers also tested whether kidney damage sits on the path between the metal and the deaths. It follows people over time without assigning anything, so it shows a link, not proof of cause, and it is a preprint that has not been peer reviewed.
