Characteristics of the study population according to tertiles of estimated 24-h sodium excretion.

Data presented as mean ± standard deviation or n (%) for categorical variables§: The difference between 1st and 2nd: p †: The difference between 1st and 3rd: p ‡ The difference between 2nd and 3rd: p E24UNA, Estimated 24-hour urine sodium excretion; BMI, body mass index; ASM, appendicular skeletal mass; SBP, systolic blood pressure; DBP, diastolic blood pressure; LDL, low-density lipoprotein; HDL, high-density lipoprotein; AST, aspartate aminotransaminase; ALT, alanine aminotransferase; GGT, gamma-glutamyl transferase; HTN, hypertension; FLI, fatty liver; HSI, hepatic steatosis indexCharacteristics of the study population according to tertiles of estimated 24-h sodium excretion.分类变量以均值±标准差或例数（百分比）呈现，其中§代表第一分位与第二分位的组间差异检验p值，†代表第一分位与第三分位的组间差异检验p值，‡代表第二分位与第三分位的组间差异检验p值。 术语定义如下：E24UNA（Estimated 24-hour urine sodium excretion，估算24小时尿钠排泄量）、BMI（body mass index，身体质量指数）、ASM（appendicular skeletal mass，四肢骨骼肌质量）、SBP（systolic blood pressure，收缩压）、DBP（diastolic blood pressure，舒张压）、LDL（low-density lipoprotein，低密度脂蛋白）、HDL（high-density lipoprotein，高密度脂蛋白）、AST（aspartate aminotransaminase，天冬氨酸氨基转移酶）、ALT（alanine aminotransferase，丙氨酸氨基转移酶）、GGT（gamma-glutamyl transferase，γ-谷氨酰转移酶）、HTN（hypertension，高血压）、FLI（fatty liver，脂肪肝）、HSI（hepatic steatosis index，肝脂肪变性指数）。 本研究呈现按估算24小时尿钠排泄量三分位分组的研究人群特征。
