Circulating GLP-1 Levels in Patients with Pheochromocytoma/Paraganglioma

Table 3

Plasma MNs and GLP-1 levels of study patients before and after surgery (n = 13).

Before surgeryAfter surgery

Plasma MN (nmol/l)0.30 (0.15–2.84)0.12 (0.08–0.21)0.007
Plasma NMN (nmol/l)8.42 (4.51–20.56)0.48 (0.43–0.56)0.001
Fasting total GLP-1 (pmol/l)25.81 ± 15.8339.01 ± 19.560.017

The significance of differences between preoperative and postoperative values was analyzed using paired Wilcoxon or paired t-tests. Data are shown as mean ± SD or the median (internal quartile range (IQR)). GLP-1: glucagon-likepeptide-1; MN: metanephrine; NMN: normetanephrine.
