Our study was performed in 66 infants and mothers. The mothers of 23 infants with cow's milk-related colic were asked to participate in the double-blind crossover trial, and 16 accepted. The results of the trial were expressed according to the rules of sequential analysis, a statistical method considered to be useful in a study like ours (references to the method were given in our paper). According to these rules the study should be completed as soon as any line of the sequential chart had been passed.
