Association between sarcopenia and the foot-ankle function in type 2 diabetic foot ulcer

Table 1 Comparison of clinical characteristics between the Sarcopenia and non-sarcopenia groups in DF ulcer patients

	DF with sarcopenia (n = 44)	DF without sarcopenia (n = 64)	t/Z/χ² value	P value
Gender (male/female)	77.3%/22.7%	59.4%/40.6%	3.759	0.053
Age (years old)	67.27 ± 7.93	61.09 ± 9.43	3.565	0.001^*
BMI (kg/m²)	21.80 ± 2.45	24.57 ± 3.21	-4.83	< 0.001^*
Duration of diabetes (years)	18.5 (10, 20)	10 (6, 19.5)	-2.972	0.003^*
Duration of DF (days)	20.5 (14.25, 60)	15 (10, 41.25)	-1.154	0.249
Wagner classification (1/2/3 /4/5)	13.6%/27.3%/29.5% 25%/4.5%	31.3%/43.8%/14.1% 10.9%/0	13.733	0.005^*

Gender was assessed using the chi-squared test; Wagner classification was evaluated using Fisher’s exact test; age and BMI were analyzed using the t-test, while the duration of diabetes and DF disease course were examined using non-parametric tests. *P < 0.05 indicates statistical significance. DF, diabetic foot; BMI, body mass index
