** type protective statistically significant association for patients all JIA subjects
Results are only shown for those alleles where there was evidence for a difference between JIA subgroups.
Bold-face type highlights statistically significant associations for patients all JIA subjects;
gf (allele frequency), P (probability), OR (odds ratio) and x² values of OR are reported only for significant associations ( P < 0.05)
