90th Percentile of the Absolute Mean Difference (AMD_90) for RMD_race+ with Three Levels of Induced Missingness
| Percent Missing: | 5% | 10% | 20% | |
|---|---|---|---|---|
| Variable | Simple | RMD_race++ | RMD_race++ | RMD_race++ |
| NonWhite (%) | 7.2 | 3.2 | 3.8 | 4.9 |
| Female (%) | 0.7 | 0.6 | 0.6 | 0.7 |
| On Statins (%) | 1.8 | 1.2 | 1.3 | 1.5 |
| Systolic BP (mmHg) | 0.8 | 0.8 | 0.8 | 0.8 |
| BMI | 0.3 | 0.1 | 0.1 | 0.2 |
| A1c (%) | 0.1 | 0.1 | 0.1 | 0.1 |
| N patients | 60.5 | 33.8 | 37.4 | 44.5 |
90 sites matched. Balance is for the true covariate values without missingness. Missingness was induced completely at random (MCAR) over all 7 covariates. RMD_race++ has weights=10 for race and BMI, 5 for statin use and N patients, and 1 otherwise. 10,000 simulations run for each method. Standard errors for N patients are ≤0.7 and ≤0.1 for all other variables.
