Additional file 3: Table S3. of Determinants of difficulty in activities of daily living in ambulatory patients undergoing hemodialysis

Univariate and multivariate logistic regression analyses on ADL difficulty. Univariate and multivariate logistic regression analyses were performed with ADL difficulty as a dependent variable and age, male sex, blood hemoglobin concentration, serum albumin concentration, comorbidity index, depression symptoms, maximum leg strength, one-leg standing time, and usual walking speed as independent variables for each level. *ADL items with higher level difficulty included “walking up two flights of stairs,” “walking 1 km,” “walking 600 m,” and “rising from the floor.” †ADL items with middle level difficulty included “walking down two flights of stairs,” “walking 300 m,” “walking up one flight of stairs,” and “sitting down on the floor.” ‡ADL items with lower level difficulty included “walking 20 m quickly,” “walking down one flight of stairs,” “walking 100 m,” and “rising from a chair.” ADL, activities of daily living; OR, odds ratio; CI, confidence interval.

本研究针对日常生活活动（Activities of Daily Living, ADL）能力障碍开展单因素及多因素logistic回归分析：以ADL能力障碍为因变量，以年龄、男性性别、血液血红蛋白浓度、血清白蛋白浓度、共病指数、抑郁症状、最大腿部肌力、单腿站立时长及日常步行速度为自变量，针对各难度层级实施分析。
* 高难度ADL条目包括：“攀爬两段楼梯”“步行1公里”“步行600米”及“从地面起身”。
† 中难度ADL条目包括：“下两段楼梯”“步行300米”“攀爬一段楼梯”及“坐至地面”。
‡ 低难度ADL条目包括：“快速步行20米”“下一段楼梯”“步行100米”及“从椅子起身”。
注：ADL即日常生活活动，OR为优势比（Odds Ratio），CI为置信区间（Confidence Interval）。（XLSX格式，文件大小15 KB）
