Table 3.

Posterior mean AUC and 95% CIs for discriminating small-for-gestational-age using estimated fetal weight at different levels of BMI, the Fetal Growth Studies. NO: no constraint; SO: stochastically ordered constraint that visit 4 has higher accuracy than visit 3, Mean: posterior mean; CI: credible interval
