Association between circulating betatrophin levels and T2DM: a meta-analysis

Introduction:
The association between betatrophin level and type 2 diabetes mellitus (T2DM) is a subject of controversy, and the reasons for conflicting results have been poorly explained. To address this gap, we conducted a meta-analysis of relevant studies to obtain a more comprehensive estimate and draw a more accurate conclusion.
Evidence Acquisition:
This study included literature published up to June 2023. We searched for relevant studies in the Web of Science and PubMed databases. We utilized STATA 12.0 software to calculate the standard mean difference (SMD) and 95% confidence interval (CI) to compare circulating betatrophin levels between individuals with T2DM and healthy controls (HCs).
Evidence Synthesis:
The meta-analysis revealed a significantly higher circulating betatrophin level in individuals with T2DM compared to HC, using a random effects model [mean value of betatrophin level (T2DM vs. HC): 388,685.23 vs. 304,857.04 pg/mL; SMD=1.37; 95%CI: 1.01, 1.73]. Subgroup analysis indicated a higher circulating betatrophin level in T2DM compared to HC among Asian individuals, while no significant difference in circulating betatrophin level was observed between T2DM and HC among Caucasian individuals (Asian: SMD=1.65; 95%CI: 1.23, 2.06; Caucasian: SMD=0.50; 95%CI: -0.21, 1.20). Additionally, subgroup analysis revealed increased plasma and serum betatrophin levels in T2DM compared to HC (plasma: SMD=1.30; 95%CI: 0.72, 1.88; serum: SMD=1.47; 95%CI: 0.98, 1.96).
Conclusions:
This meta-analysis provides evidence of elevated levels of betatrophin in individuals with T2DM, suggesting that betatrophin may serve as a potential diagnostic biomarker for T2DM.
