Table 3 Multivariable linear regression between change in body weight with change in regional peak plantar pressure and change in foot pain

From: Increase in body weight over a two-year period is associated with an increase in midfoot pressure and foot pain

i) Plantar pressuresa Unstandardised B coefficients (95% CI) p value
 Whole foot 2.151 (−2.275 to 7.186) 0.302
 Heel 2.921 (−0.940 to 6.782) 0.135
 Midfoot 4.648 (0.273 to 9.024) 0.038
 Forefoot 2.230 (−2.231 to 6.691) 0.319
 Hallux 1.444 (−3.046 to 5.935) 0.521
 Lesser toes 4.303 (−1.032 to 9.638) 0.111
ii) Manchester Foot Pain and Disability Indexb   
 Pain intensity subscale 0.216 (−0.611 to 1.044) 0.601
 Functional limitation subscale 0.409 (0.101 to 0.717) 0.010
  1. Each region and pain subscale was analysed independently. The change in foot pain intensity and functional limitation units are Manchester Foot and Disability Index Rasch transformed scores (pain intensity and functional limitation domains)
