Research by the DAMASK Trial Team, Cost-effectiveness of magnetic resonance imaging of the knee for patients presenting in primary care. Br J Gen Pract 2008; DOI: https://doi.org/10.3399/bjgp08X342660 showed mean QALYs over 24 months as difference = 0.050 and 95% CI = 0.025 to 0.118 in the Abstract and Table 4. The lower CI is missing a minus, and it should read −0.025 to 0.118, around a difference of 0.050. The online version has been corrected.
