Adjusted mean handgrip strength, walking velocity and ADL according to the severity of the anaemia

	Severe anaemia (n = 37)	Moderate anaemia (n = 69)	No anaemia (n = 114)	P
Adjusted mean premorbid ADL, score	3.50 (2.5–4.47)	3.05 (2.30–3.80)	3.30 (2.71–3.88)	0.75
aadjusted mean handgrip strength, kg	17.3 (14.4–20.2)	19.9 (17.7–22.1)	19.1 (17.3–20.8)	0.38
badjusted mean gait speed, m/s	0.57 (0.45–0.70)	0.52 (0.43–0.60)	0.47 (0.4–0.54)	0.28

Data presented as mean (95 % CI) and adjusted for sex, age, body mass index, mini mental state examination, estimated glomerular filtration ratio, clinical diagnosis and number of comorbidities

Abbreviations: ADL activities of daily living

Severe anaemia: haemoglobin <10 g/dL; moderate anaemia: haemoglobin between 10 and 12 g/dL for women and between 10 and 13 g/dL for men; no anaemia: haemoglobin ≥12 g/dL for women and ≥13 g/dL for men

^aData for hand grip strength were available in 209 patients (104 patients with and 105 without anaemia)

^bData for gait speed were available in 97 patients (42 patients with and 55 patients without anaemia)
