Neurological Sciences, 03/02/2012
Kuper M et al. – Differences did not reach statistical significance between the three groups (p = 0.564 for right left shunts (RLS) prevalence, p = 0.349 for prevalence of permanent shunts). The data implicate a trend towards higher prevalence of RLS with larger shunts in subjects with migraine with aura.
