Donor site morbidity after computer assisted surgical reconstruction of the mandible using deep circumflex iliac artery grafts: a cross sectional study

Table 6 Spearman’s rank correlation coefficients for patient specific factors age (in years), follow-up interval (in weeks), length of skin incision (in cm), graft diameter (in cm), graft volume (in cm³) and difference of ROM of the hip joint between the operated and the unaffected side

Difference of ROM	Age	Follow-up	Skin incision	Graft diameter	Graft volume
In extension (°)	− 0.530	− 0.064	− 0.042	− 0.255	0.094
In flexion (°)	0.086	− 0.193	0.095	− 0.135	0.011
In abduction (°)	0.656	− 0.025	0.32	0.104	0.007
In adduction (°)	0.344	− 0.331	− 0.244	0.048	0.265
In internal rotation (°)	0.219	0.092	− 0.167	0.162	− 0.594
In external rotation (°)	0.169	0.255	0.378	0.373	− 0.408

Significance level of the correlation is given by the according p-value. p-values ≤ 0.05 are written bold
