Fig 1 Preoperative plasma and urine catecholamines and metanephrine levels of 16 patients with functional paragangliomas. Values are expressed as standardized scores: measured catecholamine or metanephrine level minus upper limit of normal (UNL [reference]) divided by UNL. The overall maximum concentrations of catecholamines are coming from norepinephrine or its metabolites. The dotted line at 0 indicates upper limit of reference range. All individual measurements are presented. The box-and-whisker plots show 25th and 75th percentiles, with median (middle bar) and mean (diamond). The lowest datum for whiskers is within 1.5 interquartile range of the lower quartile, and the highest datum is within 1.5 interquartile range of the upper quartile.
