The authors of this Research paper would like to point out that a calculation error resulted in an inaccuracy in the figure, which shows the flow of participants through the study (BMJ 2012;345:e6564, doi:10.1136/bmj.e6564). For patients with a Wells score ≤4 (n=422), but a positive point of care D-dimer (n=150), the total number of venous thromboembolic events should be 17 (not 25, as published).
