A Typical 1H nuclear magnetic resonance spectrum. 6. lactate; 7. alanine; 8. acetate; 9. lipid; 10. glutamine; 11. acetone; 12. acetoacetate; 13. pyruvate; 14. citrate; 15. creatine; 16. choline; 17. glucose; 18. tyrosine; 19. phenylalanine; 20. methylhistidine; 21. fructose; 22. 3-hydroxyisovalerate; 23. dimethylamine; 24. asparagine; 25. N, N-dimethylglycine; 26. creatinine; 27. malonate; 28. carnitine; 29. betaine; 30. theophylline; 31. taurine; 32. glycine; 33. threonine; 34. fructose; 35. tartrate; 36. Fumarate; 37. tyrosine; 38. vanillate; 39. histidine; 40. tryptamine; 41. 3-indoxyl sulfate; 42. hippurate; 43. hypoxanthine; 44. formate; 45. trigonelline; 46. 1-methylnicotinamide. Score scatter plots of orthogonal partial least-squares discriminant analysis and variable importance in projection shows a difference between B community-acquired pneumonia with and without acquired respiratory distress syndrome groups; and C before and after treatment in the community-acquired pneumonia with acquired respiratory distress syndrome group.
