Table 1.

Results from 1000 simulated datasets of N = 500 cases and M = 1 control per case with MCAR missingness mechanism. “LOR” is mean estimated log odds ratio, “SE” is empirical standard error, “estSE” is mean estimated standard error, “MSE” is mean-squared error ×1000, and “cv” is coverage of 95% confidence interval. True log odds ratios are 0.417, 0.333, and 0.333 for X^cat, X^conA, and X^conB, respectively.
