Circulating GLP-1 Levels in Patients with Pheochromocytoma/Paraganglioma

Table 2

Multiple linear regression analyses for the association of plasma GLP-1 levels with plasma-free MN.

	Regression analysis
	Unadjusted coefficient β(95% CI)		Adjusted coefficient β(95% CI)
Plasma MN	−0.407 (−0.444–−0.031)	0.026	−0.493 (−0.508–−0.067)	0.013

Multivariate analysis was performed by linear regression adjusting for potential confounders such as age, gender, BMI, hyperglycemia, and serum creatinine. Data were logarithmically transformed to approximate a normal distribution. MN: metanephrine.
