Hello,  


Randomized controlled trials with more than 20% lost to follow up have serious validity issues.  Thus,  


I consider this study invalid. Also how many were breastfed exclusively vs formula fed .  How many had


a diagnosis of colic/reflux.  We should not be comparing how much time one group is crying to another 


but amount of crying before and after the intervention.  So not mean hours but mean increase or decrease


after the intervention.
