Ex Input:
Question: Do novel meta-analysis-derived type 2 diabetes risk loci determine prediabetic phenotypes?
Answer: In contrast to the first series of GWA-derived type 2 diabetes candidate SNPs, we could not detect reliable associations of the novel risk loci with prediabetic phenotypes. Possible weak effects of ADAMTS9 SNP rs4607103 and VEGFA SNP rs9472138 on insulin sensitivity and insulin secretion, respectively, await further confirmation by larger studies.

Ex Output:
no


Ex Input:

Ex Input:
Question: Do ethnicity and OPRM variant independently predict pain perception and patient-controlled analgesia usage for post-operative pain?

Ex Output:

yes
