Can immediate postoperative radiographs predict outcomes in pediatric clubfoot?

Table 1 Demographic data for the excellent/good and fair/poor functional groups

Demographic data	Excellent and good group (n = 36)	Fair and poor group (n = 18)	Mean different (95%CI)	P value
Male, n (%)	26 (72.22)	11 (61.11)	-	0.407b
Number of casts	8.69 (3.05)	8.33 (3.39)	-0.36 (-2.19, 1.47)	0.6950a
Age at tenotomy (d), mean (SD)	144 (53.52)	161.55 (69.11)	17.55 (-16.66, 51.77)	0.3081a
