PLS-DA scores plots (left panels), their corresponding coefficient loading plots (middle panels) and volcano plots (right panels) derived from fecal NMR data. Variable importance projection (VIP) together with correlation coefficient of each model is introduced with being represented by circle size and color. VIP values are categorized into two segments: top 20% and rest 80% represented by a circle of larger or small size. Leu, leucine; Ile, isoleucine; Pro, propionate; 2-HB, 2-hydroxybutyrate; BA, bile acids; OIV, 2-oxoisovalerate; Arg, arginine; Val, valine; Eth, ethanol; Lac, lactate; Thr, threonine; UDP-Glc, uridine diphosphate glucose
