Figure 1

Representative 1H nuclear magnetic resonance (NMR) spectra of urine samples and discrimination between healthy control and gastric cancer groups. (A) Typical 1H NMR spectra with an internal standard signal (0.025% TSP) at 0 ppm. The left panel shows a representative 1H NMR spectrum for healthy controls, and the right panel shows a representative 1H NMR spectrum for patients with gastric cancer. (B) Orthogonal projections to the orthogonal projection for a latent structure-discriminant analysis (OPLS-DA) score plot of the healthy control and gastric cancer groups. The model was constructed with one predictive (Pp) and two orthogonal (Po) components. The overall goodness of fit and cross-validation coefficients are 86.5 and 72.8%, respectively. Black boxes: samples from healthy controls; red triangles: samples from patients with gastric cancer.
