Task: Answer Verification
Input (English): Question: Does extremes of shock index predict death in trauma patients?
Answer: Our data indicate a bimodal relationship between SI and mortality in head injured patients that persists after correction for various co-factors. The distribution of mortality is different between head injured patients and patients without head injuries. Elevated SI predicts death in all trauma patients, but low SI values only predict death in head injured patients.
Output (English): yes
