Abstract

Aims: Fatty Liver Index (FLI) is a surrogate index for diagnosis of Fatty Liver Disease (FLD). We performed a dose-response meta-analysis to investigate the relationship between FLI and diabetes incidence in prospective cohort studies.

Methods: We conducted a systematic search of articles up to November 2019 in PubMed, SCOPUS, Cochrane library, and Embase. Hazard Ratios (HRs) with corresponding 95% confidence intervals (CIs) of studies were pooled using meta-analysis with DerSimonian and Laird random-effects models to find combined HRs. Dose-response effect of this relationship was also assessed.

Results: Twenty-seven studies providing 70,918 participants were included in the meta-analysis. Pooled results showed that the highest category of FLI was associated with an increased incidence of diabetes [HR: 2.88, 95% CI: 2.18-3.81; P for heterogeneity: 0.001]. Subgroup analysis based on sex, continent, and the quality of study could not explain the source of heterogeneity. The pooled HR from the random-effects dose-response model indicated a significant association between FLI level and risk of diabetes incidence (Coef=0.0239, p=0.001).

Conclusion: Our dose-response meta-analysis revealed a direct relationship between FLI and HR of diabetes incidence.
