PM: Proportion Missing; Setup 2: Average SEs equivalent to between-study SDs. Setup 3: Average SEs one-tenth the size of between-study SDs. Reminder: Hierarchical Conditional Prior conditions on one continuous simulated trial-level summary variable. Letters (e.g. (d)) displayed correspond to those used to define missing data handling strategies introduced in-text.
