Abbreviation: AUC: Area Under Curve; ABSI: A Body Adiposity Index; BMI: Body Mass Index; BRI: Body Roundness Index; HTA: Arterial Hypertension; I2: Heterogeneity; N: number of studies included; WC: Waist Circumference; WHtR: Waist-to-Height Ratio. Note: Within the non-Chinese population, only European population were also analysed, in order to distinguish the possible influence of the various populations that make up the non-Chinese. Differences between BRI and ABSI, BMI, WC or WHtR: a p < 0.05; b p < 0.01; c p < 0.001. Differences between ABSI and BMI, WC or WHtR: * p < 0.05; † p < 0.01; ‡ p < 0.001.
