title: Association between family income to poverty ratio and nocturia in adults aged 20 years and older

description: 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.
description: 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.
description: # 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. ## Description of
 the data and file structure #### Data Seqn: The patient sequence number
 corresponding to the NHANES database. Gender: The gender of the
 participants. Age: The age range of the participants. Race: The race of
 the participants. Education: The education level of the participants.
 Marry: The marital status of the participants. PIR: The family income to
 poverty ratio of the participants. Cotinine: The concentration of cotinine
 range in participants' blood. 1 represents the concentration of
 cotinine &lt;0.015 ng/ml. 2 represents cotinine concentration between
 0.015 and 3 ng/ml. 3 represents the concentration of cotinine &gt;3 ng/ml.
 BMI: Categorical range of the participant's Body Mass Index. Drink:
 The response to “Had at least 12 alcohol drinks/1 year.” 0 = no, 1 = yes
 Hypertension: This indicates whether participants have hypertension. 0 =
 no, 1 = yes Diabetes: This indicates whether participants have diabetes. 0
 = no, 1 = yes Nocturia: This indicates whether participants have nocturia.
 0 represents the participant has no nocturia, and 1 represents that the
 participant has nocturia. Wtint2yr, wtmec2yr, sdmvpsu, sdmvstra: The
 original weights obtained from the NHANES database. Weight: The final
 weights obtained after analysis. #### RCS, 1.4svyscitb5, and subgroup The
 “Data” contains the data of the final selected population through our
 screening. “RCS, “1.4svyscitb5,” and “subgroup” are all run using R
 Project. Running “RCS,” restricted cubic spline regression analysis is
 conducted on the data in “Data” three times based on annotations in our
 code. Running “subgroup” and “1.4svyscitb5,” subgroup analysis is
 performed on the data in “Data” according to annotations in our code. ##
 Sharing/Access information The data we used could all be obtained through
 the NHANES database website. All indirect identifiable categories were
 anonymized to protect the identity of participants.
