Input: Consider Input: Question: Does implementing goal-directed protocols reduce length of stay after cardiac surgery?
Answer: A milestone-driven pathway supported by team rounding was associated with decreased lengths of CVICU and hospital stay. However, tracking patient trajectories by milestones suggests a more complex relationship than anticipated and presents new opportunities for SREBP implementation and research.

Output: yes


Input: Consider Input: Question: Does overexpression of long noncoding RNA HOTAIR predict a poor prognosis in patients with cervical cancer?
