    Dear Athra,
    Thanks for your presentation, and interesting to see. You present the statistical findings, but I’m also interested in the absolute and relative values underlying these statistics. What peak pressures did you see in the various regions? And how large (or small) were the relative differences you found?

      Dear Jaap, thank you for watching my presentation and for your question.
      The average absolute peak pressure values (n=10) of the different heel masks when a large radius is used are as follows: mask1=168kPa, mask2=229kPa, mask3=231kPa, mask4=195kPa, mask5=210kPa, mask6=108kPa and mask7=125kPa. The average absolute peak pressure values of the different heel masks when a small radius is used: mask1=186kPa, mask2=241kPa, mask3=244kPa, mask4=191kPa, mask5=206kPa, mask6=104kPa and mask7=121kPa.
      For the significant main effect of the rocker radius on the relative peak pressure (RPP) for the different heel masks, you have the following values: in mask 1 the average relative peak pressure is -7.6% when a large radius is used. For a smaller radius the average relative peak pressure is 1.8% with p<0.01, in mask 2 (mean RPP LR=-2.6%, SR=1.7%, p=0.03), mask 3 (mean RPP LR=-4.8%, SR=0.6%, p<0.01), mask 5 (mean RPP LR=1.6%, SR=-0.6%, p=0.04) and mask 7 (mean RPP LR=8.1%, SR=3.4%, p=0.02).
      For the significant main interaction effect between the apex position and rocker radius for mask 1 (mean RPP mid apex position + LR =-12.1%, SR=-1.2%, p=0.03), (mean RPP proximal apex position + LR= -11.7%, SR=10.9%, p<0.01), and in mask 3 (mean RPP proximal apex position + LR=-9.3%, SR=4.3%, p<0.01).
      I hope this answers your question.
      If you have other questions, I will gladly answer them.
