Popis: Abstract Objective To investigate the association of serum creatinine-cystatin C ratio (Cr/CysC) with long-term all-cause mortality and cause-specific (cardiovascular and cancer) mortality among US general adults. Methods This nationally representative cohort study included adults in the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2004. Participants were linked to National Death Index data from the survey date through December 31, 2019. Weighted Cox proportional hazards regression models were used to calculate hazard ratios and 95% confidence intervals (CIs), and restricted cubic splines and stratified analyses were also performed. Results A total of 12,914 participants were included in this study (mean [SD] age, 45.3 [17.3] years; males, 48.9%). During a median follow-up of 17.9 years (maximum follow-up, 20.8 years), 3439 total deaths occurred, including 1098 cardiovascular deaths and 736 cancer deaths. Cumulative incidence curves revealed that increased Cr/CysC ratio had lower risk of all-cause (P
