| Survey-Weighted Cox Model | Concordance (SE) | Term Tested | 2logLR | Significance |
|---|---|---|---|---|
| Base (sex + age) | .759 (.012) | Age | 678.23 | *** |
| Base + BE18 | .812 (.01) | Age | 327.22 | *** |
| BE18 | 423.07 | *** | ||
| Base + BEC18 | .812 (.01) | Age | 177.94 | *** |

Notes: HRS = Health and Retirement Study; LR = likelihood ratio. The concordance estimates the accuracy of each model. The 2logLR and significance are to assess the significance of the indicated term.
