Description
DecisionLinnc1.0 software(http://www.statsape.com.) was employed for data analysis. We analyzed the data from the NHANES, a representative cross-sectional survey of all non-institutionalized civilian populations in the United States. The National Center for Health Statistics Research Ethics Review Board authorized the NHANES study protocols in compliance with the revised Declaration of Helsinki. The NHANES data were released over 2-year cycles. To obtain a large sample for analysis, we combined eight cycles of continuous NHANES data from 2005 to 2020. The National Center for Health Statistics Ethics Review Committee granted ethics approval. All participants provided written informed consent before participating in the study. More information about the NHANES could be obtained at: http://www.cdc.gov/nhanes. Of the 85,750 participants extracted from the NHANES database, we excluded those with missing information on the hypertension questionnaire (n = 30,855), SII data (n=5,361), trouble sleeping (n = 28), aged ≥ 20 years (44,285), and other covariates (n = 20,871). Finally, a total of 23,414 participants were included in this study. Besides, the screened data are analyzed by descriptive statistics, linear regression, logical regression, intermediary effect analysis and so on.
