Association between blood urea nitrogen-to-albumin ratio and kidney stones: A cross-sectional study based on NHANES

Preprint C Not peer reviewed Observational

Key takeaways

This preprint looked at a blood test ratio called BAR and its link to kidney stones. It used data from the NHANES survey. It is an observational study, so it shows a link, not proof of cause. The study is not yet peer-reviewed, so the findings are preliminary.
