Summary statistics on perfusion in right (infected) and left (non-infected) hind limbs

VOI location	Number of pairs	Mean ± SD, mL/min/100 cm3		Ratio from logarithmica	Right vs. left*
		Right	Left
Medullary canal	11	21 ± 11	21 ± 14	1.06	p > 0.1 (NS)
Thigh muscle	11	3.8 ± 0.9	4.3 ± 1.3	0.89	p < 0.02
OM lesionsb	17	39 ± 13	26 ± 7	1.46	p < 0.002
ST lesionsc	8	41 ± 13	7.0 ± 5.4	6.1	p < 0.01

NS not significant

*Combining p values from simple and logarithmic differences, e.g. p < 0.01 means that the p value was below 0.01 for both simple and logarithmic differences. For detailed comparison results, see Additional file 1: Table S1

^aRepresenting result from logarithmic differences; e.g. for medullary canal, the mean value of logarithmic differences was 0.058, giving ratio = exp (0.058) = 1.06
