SNP rs11172113 (LRP1) in this group had mostly undifferentiated associations, except for stratum-specific associations according to aura status (for MO, beta [SE] = 0.14 [0.036], p = 8.3×105 compared with MA, beta [SE] = 0.057 [0.043], p = 0.19) and migraine duration 4–72 hours (beta [SE] = 0.12 [0.032], p = 0.00012) but not duration under four hours (beta [SE] = 0.054 [0.058], p = 0.34), as reflected also by “inverse subset” and “subset” models with the BIC (boxes with heavy solid outline in Fig. 1), respectively. This evidence concerns the gene LRP1 and migraine disorder.
