FLI was calculated at baseline for 1,142 adult subjects with prediabetes attending primary care centers, and classified into three categories: FLI The proportion of subjects with prediabetes and hepatic steatosis (FLI ≥60) at baseline was 55.7%. The incidence rate of T2D at 3 years follow-up was 1.3, 2.9 and 6.0 per 100 person-years for FLI60 and FLI ≥60, respectively. The most significant variables increasing the risk of developing T2D were metabolic syndrome (hazard ratio [HR] = 3.02; 95% confidence interval [CI] = 2.14-4.26) and FLI ≥60 (HR = 4.52; 95%CI = 2.10-9.72). Moreover, FLI ≥60 was independently associated with T2D incidence: the HR was 4.97 (95% CI: 2.28-10.80) in the base regression model adjusted by sex, age and educational level, and 3.21 (95%CI: 1.45-7.09) in the fully adjusted model. FLI may be considered an easy and valuable early indicator of high risk of incident T2D in patients with prediabetes attended in primary care, which could allow the adoption of effective measures needed to prevent and reduce the progression of the disease.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/AdultAgedAged, 80 and overBiomarkersCohort StudiesDiabetes Mellitus, Type 2Disease ProgressionFemaleHumansIncidenceMaleMiddle AgedNon-alcoholic Fatty Liver DiseasePrediabetic StatePrognosisRisk FactorsSeverity of Illness Indexresearch article29856820open access10.1371/journal.pone.01983271932-6203PMC5983533https://journals.plos.org/plosone/article/file?id=10.1371/journal.pone.0198327&type=printablehttps://www.ncbi.nlm.nih.gov/pmc/articles/PMC5983533/pdf
