Example Input: Question: Does health-related quality of life differ between short-term , long-term and very long-term cancer survivors in the Swedish general population?
Answer: Although HRQL was similar between short-term, long-term and very long-term survivors, when compared with the background population, findings suggest that some functional impairments and symptoms are present even at 5-10 YSD.
Example Output: no

Example Input: Question: Does cYP3A5 genotype influence everolimus in vitro metabolism and clinical pharmacokinetics in renal transplant recipients?
Answer: This study provides direct and indirect evidence that CYP3A5 genotyping cannot help improve everolimus therapy.
Example Output: no

Example Input: Question: Does proteomics reveal potential non-neuronal cholinergic receptor-effectors in endothelial cells?
Answer: A set of proteins differentially expressed in endothelial cells in response to cholinergic agonists may have important implications for the downstream biological effects of NNAS.
Example Output:
yes
