Protective effect of dietary phosphorus intake on cardiovascular mortality in asthma: evidence from NHANES 1999-2018.

ABSTRACT:

Background

Asthma is associated with an increased risk of cardiovascular mortality, potentially influenced by dietary phosphorus intake through its effects on inflammation and oxidative stress.

Methods

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.

Results

Higher dietary phosphorus intake was associa
