Balagopal et al. [32] reported that RBP4 was positively associated with CRP and negatively associated with adiponectin in a small group of obese children; however, no correlation between RBP4 and CRP or adiponectin was observed in another study of 101 hospitalized T2DM patients [33]. The gene discussed is RBP4; the disease is type 2 diabetes mellitus.
