Table 1 Characteristics of 132 participants according to the presence of impairment in the Activities of Daily Living (ADLs; impairment was defined as an ADLs score <6). (Study center: Catholic University, Rome, 2007–2015)

From: Functional impairment is associated with an increased risk of mortality in patients on chronic hemodialysis
