a
Only significant associations (P < 0.05) between genes are shown.
b
—, despite the presence of a significant association, the OR and the confidence interval could not be estimated reliably because of the presence of a zero in one or several of the cells in the two-by-two table used for testing pairwise associations.
c
Negative association (i.e., incompatible genes).
