Fig. 1From: Low serum sodium concentration is a prognostic factor related to current blood glucose level in stable hemodialysis patients: an observational studyNon-fasting predialysis blood glucose level was inversely related to serum sodium concentration. a–c Non-fasting predialysis blood glucose level was inversely related to serum sodium concentration in crude analysis (a), middle-aged patients (b), and older patients (c). d–f The relationship between serum sodium concentration and non-fasting predialysis blood glucose level in the patients with blood glucose level greater than or equal to 140 mg/dL in crude analysis (d), middle-aged patients (e), and older patients (f). Spearman’s coefficients are denoted by rs. The regression equation was shown in each graphBack to article page
