Ambiguity in statistical analysis methods and nonconformity with prespecified commitment to data sharing in a cluster randomized controlled trial

In a published cluster randomized controlled trial (cRCT) [1] on the effects of desks on physical behaviors, 66 individuals were randomized into 3 groups by their office space (ie, clusters): the seated desk control (n=21; 8 clusters), sit-to-stand desk (n=23; 9 clusters), or treadmill desk (n=22; 7 clusters) group.
