Preventing injuries in children: cluster randomised controlled trial in primary care

This general practice paper by Denise Kendrick and colleagues (10 April, pp 980-3) contains three errors. The calculationof sample size was based on "a mean cluster size of 60 [not 60%]"(first sentence, p 981); in table 3 (p 982) the number of childrenwho received advice at the 18-24 month check should have been535 rather than 35; and in table 4 (p 982) the number of childrenin the control group who had any medically attended injury shouldhave been 330 rather than220.
