Of the 85 included patients; 69 patients (81.2%) had low SMI, 50 patients (58.8%) had lowHGS, and 58 patients (68.2%) had low gait speed. Forty-one patients (48.2%) were classified as sar - copenic; of these patients 31 patients (75.6%) had low SMI in combination with low HGS and low gait speed, 6 patients (14.6%) had low SMI in combination with low gait speed and normal HGS, and 4 patients (9.8%) had low SMI in combination with low HGS and normal gait speed. Table 2 and table 3 show the general characteristics and the hematological and biochemical markers of the included patients according to the presence or absence of sarcopenia. Patients with sarcopenia weremost likely to smoke (77.8% versus 22.2%; LR 8.37, p=0.02), to have lower mean hemoglobin levels at diagnosis (8.09 mmol/L (SD 1.06) versus 8.67 mmol/L (SD 1.12); p=0.03) and to die (63.6% versus 36.4%; LR 5.17, p<0.01). 18
