Association between family income to poverty ratio and nocturia

Data from the National Health and Nutrition Examination Survey (NHANES) in 2005-2010, including 6,662 adults aged 20 or older, were utilized for this cross-sectional study. The baseline data was used to display the distribution of each characteristic visually. Multiple linear regression and smooth curve fitting were used to study the linear and non-linear correlations between PIR and nocturia. Subgroup analysis and interaction tests were conducted to examine the stability of intergroup relationships., We obtained data from the NHANES database website for the three cycles of 2005-2006, 2007-2008, and 2009-2010. Data analysis, including baseline characteristic distribution, logistic regression analysis, RCS curves, and subgroup analysis, was conducted using StataMP17.0 and R language 4.2.2., , # Association between family income to poverty ratio and nocturia

The “Data” originates from the NHANES database and represents the data obtained after our screening process. “RCS” includes the code for conducting restricted cubic spline regression on the data after applying weights. “subgroup” contains the code for performing subgroup analysis on the weighted dataset. “1.4svyscitb5” is utilized to weigh the dataset during subgroup analysis. Through “RCS,” “subgroup,” and “1.4svyscitb5,” we analyzed “Data” and identified a significant nonlinear relationship between PIR and nocturia. We also listed the correlations between various subgroups and their associations with PIR and nocturia.
