Fig. 8: Performance analysis of the proposed markers.
From: Molecular phenotyping of oxidative stress in diabetes mellitus with point-of-care NMR system
a The normalized concentration of oxidative stress (OS) in red blood cells, oxidative stress in urine F2-IsoP, and fasting blood glucose for obese subgroup (red) and lean subgroup (black). The oxidative stress in urine were corrected for urine creatinine concentration (F2-IsoP/Cr ratio). The statistical significance was calculated using the Student’s T-test (two-tailed, unequal variance). The data is represented by box-plot format. b The receiver operating characteristic (ROC) of the respective biomarkers; PoCT NMR (black), fasting glucose (gray), and urine F2-IsoP (red). Area under the curve (AUC) of larger than 0.8, 0.6, and 0.4 was considered as good, medium, and poor.
