Figure 5. Delay from self-reported symptom onset to emergency department arrival.
(A) All cases with recorded times (n = 1,504). The mode (chequered bar; 31%) occurred at 3–6 days; however, the delay exceeded one week for more than 25% of cases (black bars). (B) Pulmonary embolus (n = 557). The mode (29%) occurred in the <1 day period; proportion with delays exceeding one week was 17%. (C) Deep vein thrombosis (n = 947). The mode (35%) occurred at 3–6 days; proportion with delays exceeding one week was 32%. The distribution for deep vein thrombosis differed from that for pulmonary embolus (P<0.001; Kuiper’s two sample test).
