(a) The urinary 1545 cm−1 mid-infrared marker had a positive correlation with proteinuria during the time course of NTN. (b) Although the level of proteinuria increased gradually along with progression of nephritis, there was a manifest sudden drop at d28 NTN (p < 0.05) probably caused by a fall in glomerular filtration rate due to severe renal injury.
