results
Study Type 
Results Category ^{a} 
Criteria 
For GWAS 
Positive 
P < 1x10^{7} 
Negative 
P > 1x10^{5} 

Trend 
1x10^{7} < P < 1x10^{5} 

For general candidategene association study and metaanalysis 
Positive 
P < 0.05 at least for one analysis 
Negative 
P > 0.05 for all analyses 

For linkage analysis ^{b (1)} 
Positive 
LOD > 3.3 at least for one analysis 
Negative 
LOD < 1.9 for all analyses 

Trend 
1.9 < LOD < 3.3 for all analysis 

For mutational study ^{c} 
Trend 
^{ }
^{a}: literatureorigin genes with at least one
positive polymorphism were defined as ‘Positive’.
^{b}: If other statistical values were used in linkage study
instead of LOD, the criteria were referred to the Statistical Method in
original papers.
^{c}: Novel defined polymorphisms by mutational studies were classified as
‘Trend’ except a significant level was proposed.
