To the Editor As coauthors of a recent study1 on hyperbaric treatment for children with cerebral palsy (CP), we would like to comment on the editorial by Hoge and Jonas2 published in JAMA Internal Medicine. Based on the study by Miller et al,3 they draw definitive conclusions on the efficacy of compressed air and hyperbaric oxygen treatment (HBOT) for postconcussion symptoms in military personnel: that HBOT does not work, but the ritual of intervention does. Although they2 recognized that both groups treated in hyperbaric chambers had significant improvements in postconcussion symptoms and secondary outcomes compared with the control group, they2 failed to reach the most evident conclusion: that both treatments were effective.
