Combined use of rapid d-dimer testing and estimation of clinical probability in the diagnosis of deep vein thrombosis: systematic review

In the full version (on bmj.com) of this paper by Tonya L Fancher and colleagues, some data in table 3 (which shows cohort characteristics of management studies) are wrong (9 October, pp 821-4). In the second row (the study by Schutgens et al) the mean age should read 59 years [not “unknown”]; male sex, 54% [not “unknown”]; and total number of cases lost to follow up, 1 [not “15”]. The table is not included in the abridged version of the paper.
