Risk of hyperglycemia was significantly lower among the participants only in the second tertile of serum NGF compared to the reference group in both crude and adjusted models (OR = 0.278, 95% CI: 0.091-0.845 vs. OR = 0.240, 95% CI: 0.074-0.779, P trend = 0.130). Here, NGF is linked to Hyperglycemia.
