BOAST4 standard	< 65 compliance, n (%); n=128	≥ 65 compliance, n (%); n=29	P-value
Antibiotics within 1 ha	11/92 (12%)	2/18 (11%)	0.92
Debridement within 12 h for high energy injuriesb	22/71 (31%)	1/8 (13%)	0.47

Soft tissue coverage by 72 hd	67/103 (65%)	10/22 (45%)	0.09

N numbers are presented as fractions, where the numerator is the number of patients meeting BOAST4 standards and the denominator is the total group size.
