GPT and metabolic dysfunction-associated steatotic liver disease: On univariate meta-regression model (Supplemental Figure 3), when plotting log odds ratio of mean different abundance of bacterial genus for NAFLD versus control patients (y-axis) against alanine aminotransferase (ALT) or body mass index (BMI) levels age (x-axis), significant association was found between BMI and Faecalibacterium (log regression coefficient β = 2.38, P = 0.00001), and Prevotella (regression coefficient β = 1.0554, P = 0.0005).
