Table 1.

Coefficients for the regression model comparing can and human $\hat{E_{1}}$ FJC strain magnitudes as functions of species (cat versus human) and HVLA-SM site (cephalic, middle, or caudal vertebra). The coefficients fit the following equation: $\hat{E_{1}} = c_{0} + c_{1} S p + {Loc}_{1} + {Loc}_{2} S p$ , where c₀ is a constant, Sp = +1 for cat and Sp = −1 for human spines, and Loc₁ and Loc₂ vary with HVLA-SM site as specified in the table below.
