Association between initial diquat plasma concentration, severity index and in-hospital mortality in patients with acute diquat poisoning: a retrospective cohort study

Since 2016, diquat has replaced paraquat in China, resulting in increased diquat poisoning cases. However, understanding of diquat poisoning is still limited. This study aimed to investigate the relationship between initial diquat plasma concentration, severity index, and in-hospital mortality in acute diquat poisoning cases.
