original publication.
This study has been identified as potentially high impact.
OE's AI-driven High Impact metric estimates the influence a paper is likely to have by integrating signals from both the journal in which it is published and the scientific content of the article itself.
Developed using state-of-the-art natural language processing, the OE High Impact model more accurately predicts a study's future citation performance than journal impact factor alone.
This enables earlier recognition of clinically meaningful research and helps readers focus on articles most likely to shape future practice.
Liberal versus restrictive blood transfusion strategy: 3-year survival and cause of death results from the FOCUS randomised controlled trial
Lancet. 2014 Dec 9. pii: S0140-6736(14)62286-8.Two thousand and sixteen patients over the age of 50 undergoing hip fracture surgery at 47 different hospitals in the United States of America and Canada were randomized to receive either liberal blood transfusions, to maintain hemoglobin level at or above 100g/L, or restrictive blood transfusions, for patients with symptoms of anemia or if hemoglobin levels were below 80g/L. Mortality rates and cause of death of the patients who died during the trial period were determined at the end of each calendar year for an overall time of 3.1 years. Results of this study indicate that there is no significant difference in survival rates between groups, nor is there a difference in the cause of death when considered in proportion to the overall population although latent effects on cancer recurrence need further investigation.
