Experiment Characteristics

Sample size: planned number of clusters
Ideally N=300 but difficulty in recruitment may force us to revise downward. We will reassess in December 2022 before looking at the data or analyzing it in any way.
Sample size: planned number of observations
See above.
Sample size (or number of clusters) by treatment arms
Equal in each arm
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
