biostudies-literatureUnknown12Yang S<h4>Background</h4>Asthma is associated with an increased risk of cardiovascular mortality, potentially influenced by dietary phosphorus intake through its effects on inflammation and oxidative stress.<h4>Methods</h4>Data from 7,539 asthma patients in the National Health and Nutrition Examination Survey (NHANES) 1999-2018 cohort were analyzed using weighted Cox proportional hazards models to estimate hazard ratios (HR) and 95% confidence intervals (CI). Kaplan-Meier survival curves and a nomogram were used to assess survival probabilities and individualized risk, while restricted cubic spline (RCS) analysis evaluated non-linear dose-response relationships. Sensitivity analyses were conducted to test the robustness of the findings.<h4>Results</h4>Higher dietary phosphorus intake was associaFrontiers in nutrition1533514https://www.ebi.ac.uk/biostudies/studies/S-EPMC11893399biostudies-literatureProtective effect of dietary phosphorus intake on cardiovascular mortality in asthma: evidence from NHANES 1999-2018.PMC11893399Zhang NChen HYang SXie CfalseProtective effect of dietary phosphorus intake on cardiovascular mortality in asthma: evidence from NHANES 1999-2018.<h4>Background</h4>Asthma is associated with an increased risk of cardiovascular mortality, potentially influenced by dietary phosphorus intake through its effects on inflammation and oxidative stress.<h4>Methods</h4>Data from 7,539 asthma patients in the National Health and Nutrition Examination Survey (NHANES) 1999-2018 cohort were analyzed using weighted Cox proportional hazards models to estimate hazard ratios (HR) and 95% confidence intervals (CI).
