<span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">'''Clinical Bottom Line:''' </span><br />
<span style="font-family: arial,helvetica,sans-serif; font-size: 120%;">1. Application of hyperbaric oxygen resulted in complete or partial relief of headache in significantly more patients than a placebo pressure exposure. </span><br />

<br />
<span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">'''Clinical Scenario:''' A patient with migraine headache. </span><br />
<span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">'''Three-part Question:''' For patients with acute migraine headache, does the application of hyperbaric oxygen therapy compared with standard prescribed therapy, result in any amelioration of the symptoms. </span><br />
<span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">'''Search Terms:''' Hyperbaric oxygenation, headache/migraine. </span><br />
<br />
<span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">'''The Study:''' </span><br />
<span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">Double-blinded concealed randomised controlled crossover trial without intention-to-treat. Adult patients with an established diagnosis of migraine for one year and suffering an acute headache at the time of study. Compliance with prescribed medication, but no narcotics during the attack under study. </span><br />
<span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">'''Control group''' (N = 10; 10 analysed): Prescribed medication (not specified) and sham hyperbaric oxygen therapy on air at 2ATA for 45 minutes. </span><br />
<span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">'''Experimental group''' (N = 9; 9 analysed): As above, but hyperbaric oxygen at 2ATA for 45 minutes. </span><br />
<br />
<span style="font-family: Arial,Helvetica,sans-serif; font-size: 120%;">'''The Evidence:''' </span><br />
