Cross-sectional correlation analyses between baseline serum sodium level and patient characteristics.

*Data for ferritin, CRP, and residual GFR were log-transformed.BMI, body mass index; CCI, Charlson Comorbidity Index score; Na, sodium; K, serum potassium; tCO2, serum bicarbonate; CRP, C-reactive protein; GFR, glomerular filtration rate; PD UF, peritoneal dialysis ultrafiltration; nPCR, normalized protein, LBM, percentage of lean body mass.Cross-sectional correlation analyses between baseline serum sodium level and patient characteristics.铁蛋白（ferritin）、C反应蛋白（CRP）及残余肾小球滤过率（residual GFR）的数据均经对数转换处理。 身体质量指数（BMI, body mass index）；查尔森合并症指数评分（CCI, Charlson Comorbidity Index score）；钠（Na, sodium）；血清钾（K, serum potassium）；血清碳酸氢盐（tCO2, serum bicarbonate）；C反应蛋白（CRP, C-reactive protein）；肾小球滤过率（GFR, glomerular filtration rate）；腹膜透析超滤量（PD UF, peritoneal dialysis ultrafiltration）；标准化蛋白（nPCR, normalized protein）；瘦体重百分比（LBM, percentage of lean body mass）。 本研究针对基线血清钠水平与患者临床特征之间开展了横断面相关性分析。
