Fig. 2From: Peritoneal dialysis assists residual renal function to maintain glucose tolerance: a prospective observational studyDaily glucose concentration (GC) profile based on continuous glucose monitoring (CGM) in non-diabetic end-stage renal disease (ESRD) patients. a Daily CG profile for each ESRD patient without diabetes before peritoneal dialysis (PD) initiation (n = 14). b Daily CG profile for each ESRD patient without diabetes after PD initiation (n = 14). The x-axis represents the time at which GC was measured. The y-axis represents GC level. Each line corresponds to the result of one subject. The GC range of 70–140 mg/dL is shadowed in blue in the graph. The daytime period, which ranges from 0800 h to 2000 h, is indicated by a box on the x-axisBack to article page
