Source:  Source of case population -> “CL” (clinic-based), “PO” (population-based), or “CO” (community-based).
# Polys:  Number of polymorphisms tested per gene and per sample.
Onset Age and Age:  Mean or median age at onset or examination, respectively.
DX:  Criteria used to determine AD diagnosis -> "C" (clinical AD diagnosis), "N" (neuropathological AD diagnosis), "M" (mixed, i.e. AD sample contains both clinical and neuropathological cases), "U" (unknown).
Result:  Overall conclusion reached by authors of the original publication (“positive” usually indicates significant (P<0.05) association in at least one of the performed analyses, and “negative” indicates no evidence for significant association, while “trend” indicates results in between); results obtained in duplicate or largely overlapping samples are listed as "n.a.".
(-) :  Either no data provided or in case of overlap, data included in original study.
