  1. Two by two tables comparing characteristics with recommendation are presented along with p-values using Fisher’s exact test (<0.05 marked with *). Rec NI for 1% group = recommended routine neuroimaging for the 1% risk group; Rec no NI for 1% group = recommended against routine neuroimaging for the 1% risk group.
