Table 1 Characteristics of participants categorized by body mass index

From: Interaction between body mass index and serum uric acid in relation to blood pressure in community-dwelling Japanese men

  1. Data for triglycerides, fasting plasma glucose, aspartate transaminase, and γ-glutamyl transpeptidase were skewed and are presented as median (interquartile range) values, and were log-transformed for analysis. P-value: Student’s t-test for continuous variables or the χ2 -test for categorical variables. Bolded numbers indicate significance
  2. CVD cardiovascular disease, HDL high-density lipoprotein, LDL low-density lipoprotein, eGFR estimated glomerular filtration rate. Data presented are mean ± standard deviation
  3. aDaily alcohol consumption was measured using the Japanese liquor unit in which a unit corresponds to 22.9 g of ethanol, and the participants were classified into never, occasional, light daily (< 2 unit/day), and heavy daily drinkers (≥ 2 unit/day)
  4. bSmoking status [never-smoker, past-smoker, light smoker (< 30 pack · year), and heavy smoker (≥ 30 pack · year)]
