Bias, MSE, and 95% coverage probability of the proportional treatment effect of 20% (4‐year trial only) for PcLDA with random effects

	No Dropout			10% Annual Dropout
Sample Size/Arm	Bias	MSE	CP	Bias	MSE	CP
100	−0.0041	0.0058	95.6%	−0.0032	0.0084	93.8%
200	−0.0007	0.0028	95.2%	−0.0027	0.0037	94.9%
300	−0.0017	0.0018	96.8%	−0.0027	0.0025	94.4%

Bias is the mean of the difference between the estimated parameter and its true value (1000 replicates). Abbreviations: CP, coverage probability of the corresponding 95% confidence interval; MSE; mean of the squared error; PcLDA, proportional constrained longitudinal data analysis model.
