EJNMMI Research

Table 2 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 logarithmic^a	Right vs. left*
VOI location	Number of pairs	Right	Left	Ratio from logarithmic^a	Right vs. 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 lesions^b	17	39 ± 13	26 ± 7	1.46	p < 0.002
ST lesions^c	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
^bOnly long bones (not patella), primary data in Table 3
^cPrimary data in Table 4
