Agreement between granulation response and final closure in advanced diabetic foot ulcer patients

		Wound closure during follow‐up		+ predictive value (%)	Sensitivity (%)
		Lesion closed	Lesion not closed	–predictive value (%)	Specificity (%)
Two weeks granulation response	≥50%	76	21	78·4%	81·7%
	<50%	17	35	67·3%	62·5%
End‐of‐treatment granulation response	Complete	90	18	83·3%	96·8%
	Not complete	3	38	92·7%	67·9%

Kappa statistics were significant (P < 0·001) for both correlation analyses. All percentages have 95% confidence limits ≤ 1%.
