Venn diagram showing the associations between QTLs and platelet function. SNPs in 15 QTLs showed an association with one or more of the platelet function measurements at the P < .005 level and with a MAF > 0.01. The gene names of the QTLs are distributed among this Venn diagram according to the functional traits (PA, FA, PC, or FC) with which they are associated. Association with platelet functional measurement for each QTL, is shown by the colored squares that indicate the level of significance from blue (P < .10), green (P < .05), yellow (P < .01), gold (P < .005), light orange (P < .0005), dark orange (P < .001), and red (P < .0001).
