Analytes with signal intensities indicating renal elimination or association to hemodialysis.

Seven of the analytes could be identified by gas chromatography/mass spectrometry (TD-GC/MS). The remaining analytes are described by data of retention time (tR) and ion mobility (1/K0). Group A: healthy controls; group B: chronic renal failure corresponding to an eGFR of 10–59 ml/min per 1.73 m2; group C: end-stage renal disease (ESRD) prior to hemodialysis; group D: ESRD after hemodialysis. Signal intensities were checked for intergroup differences by univariate ANOVA, p
