Figure S1 - IgG Abnormality in Narcolepsy and Idiopathic Hypersomnia

Influence of smoking for total IgG level (mg/ml). Subjects who smoke more than one cigarette per day are included in smoking group. Horizontal lines and squares indicate the mean ± SD. Numbers in graph indicate subject numbers in each group (female number is in parentheses). *P<0.05 vs non-smoking controls negative for HLA-DQB1*0602 (p values are as follows; smoking controls negative for HLA-DQB1*0602; p = 0.012, smoking controls positive for HLA-DQB1*0602; p = 0.005, smoking or non-smoking narcolepsy; p<0.0001). +P<0.005 vs IHS (p values are as follows; smoking controls negative for HLA; p<0.0005, smoking or non-smoking HLA-positive controls; p<0.005 and p<0.005, smoking or non-smoking narcolepsy; p<0.00001).
