  2. Notes: ADL* indicates an ADL disability. AUC denotes the area under the ROC curve and measures the detection accuracy towards ADL*. CV denotes the cut-off value at which the explanatory variable has to be split to explain ADL*. OR denotes the odds ratio. 95%-CI indicates the 95% confidence interval of the odds ratio
