Figure 1

Dot plots showing normalized logarithmic distributions of plasma concentrations of methoxytyramine (panel A) and dopamine (panel B) and urinary outputs of dopamine (panel C) in patients with PPGLs according to presence or absence of metastases. Values for disease secondary to tumors with an exclusive adrenal location are illustrated by empty circles (○). Values for disease secondary to tumors with extra-adrenal locations are illustrated by solid circles (●). The dashed horizontal lines show the upper reference limits determined from 97.5 percentiles of the reference population, as indicated by the displayed values to the upper left of dashed lines in nmol/L (see also Table 1).
