Table 2. Quadriceps muscle thickness, 60s sit-to- stand test, distance covered in meters on the 6MWT and its predicted percentage, handgrip strength absolute values, and presence of muscle weakness in CKD patients.

Variables	Patients (n=40)
	Mean (95%CI)/n (%)
Quadriceps thickness (mm)	23.92 (22.43 - 25.41)
60s-STS	22.93 (21.62 - 24.23)
DT on 6MWT(m)	471.23 (445.97 - 496.48)
DT%	82.64 (79.23 - 86.05)
Handgrip strength (kg)	33.27 (28.79 - 37.76)
% Handgrip strength	81.13 (73.42 - 88.84)
Muscular weakness	10 (25%)

60s-STS = 60s Chair sit-to-stand test; DT = distance traveled; 6MWT: six-minute walk test.
