They are perceived as being feasible only for evaluating relatively simple, standardised and unvarying interventions and thus as being too rigid and inappropriate for public health settings.33,34Such criticisms of the RCT are based on a consideration of “classic” RCTs in which the intervention is standardised and the individual is the unit of randomisation.

Warm fuzzy mittens can be put over gloves on the coldest days to keep little hands warm, too.
