The National Health Service in Ballerup (Copenhagen, Denmark) conducted a study involving 50 infants with diagnoses infantile colic.  Half of the group was given the drug dimethicon while the other half was given chiropractic care.  In this study nine of the 25 taking the drug dropped out of the study because the infants were getting worse.  These infants were then not counted in the final results which would have shown a worse result for the drug than published. Even with the removal from the tabulations of the infants who got worst using the drug, the results showed a significant improvement in the group that were under chiropractic care.  By days 4 to 7 of the study, the infants remaining in the drug group had reduced their hours of crying by only one hour while the entire chiropractic group had reduced crying hours by an average of 2.4 hours.  The results after 8 to 10 day into the study continued to show the drug therapy infants at a one hour improvement while the chiropractic group further improved to 2.7 hours less of crying.  The researchers noted that the removal from the study of the infants that got worse from the drug made the results from the drug look better than they actually were.  In the group that received chiropractic care, there was complete resolution of symptoms in 93% of the infants within the two-week period. Even more impressive was that in a follow up survey performed one month later, none of the infants had experienced a reoccurrence of problems from colic. The chiropractic care rendered in this study was spinal adjusting.
