Table 2 Summary statistics on perfusion in right (infected) and left (non-infected) hind limbs

From: Blood perfusion in osteomyelitis studied with [15O]water PET in a juvenile porcine model

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
  1. NS not significant
  2. *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
  3. 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
  4. bOnly long bones (not patella), primary data in Table 3
  5. cPrimary data in Table 4
