ABC of arterial and venous disease: swollen lower limb (part 1—general assessment and deep vein thrombosis)

Two errors occurred in this article by W Peter Gorman and colleagues (27 May, pp 1453-6). In the algorithm (p 1454), a small but important word (“or”) was missing: the right hand arrow from the box “Consider clinical probability” should go to “Moderate or high” (not just “High”). Under the section on treatment (p 1455) the fifth sentence of the second paragraph should read: “The activated partial thromboplastin time should be checked six hourly until the target is reached and then daily to maintain the ratio [not the international normalised ratio] of activated partial thromboplastin time to control at 1.5 to 2.5.”
