These tables show the statistical results corresponding to analyses 1 – 6. The fixed effects tests are presented with test statistic and probability value. Least squares estimates for selected explanatory variables are also provided. Because of the heterogeneous nature of the “Other” race category and the resulting very small counts patients who fell into the “Other” race category were not included in analyses that used race as explanatory variable.
