A list containing a data frame of overlap information and the variant intersection set.
The overlap information table (overlap_info) consists of the following columns:
studyId: Character vector. Study ID.
traitReported: Character vector. Reported trait.
traitCategory: Character vector. Trait category.
variantIdA: Character vector. Variant ID from study A.
variantIdB: Character vector. Variant ID from study B.
overlapAB: Integer vector. Number of overlaps between variants A and B.
distinctA: Integer vector. Number of distinct variants in study A.
distinctB: Integer vector. Number of distinct variants in study B.
study.studyId: Character vector. Study ID from study list.
study.traitReported: Character vector. Reported trait from study list.
study.traitCategory: Character vector. Trait category from study list.
The variant intersection set (variant_intersection_set) is a character vector representing the intersection of variants.
