Table 4.
Summary of the most explanatory multiple regression models of creep measurements. Each cell shows r2adj followed by the predictor(s) in the model (sign of estimate, parameter name, p-value in each row). If a BMD variable was found to be significantly correlated to a creep variable, the BMD variable was introduced first and forced to stay in the model. NS indicates no significant models.
