Each of the 4 columns is based on a separate linear mixed effect model. The model coefficients are interpreted with respect to a female participant 73 years old at baseline, with 15 years of education. Age was centered at 73 years and BMI at 30. Each cell shows the Estimate (Standard Error, p Value) for a different term included in the model. All 4 models included the same 7 terms (highlighted in gray) shown in Model 1 in Table 2. In contrast to the models in Table 2, each of the 4 models in this table added additional terms (highlighted in blue) to the basic model in order to examine whether chronic health conditions (Model 1A and 1B), physical activity (Model 1C) and body composition (Model 1D) accounted for either the level or rate of change of global motor scores in older African American adults.
