(a) Median serum levels of bHCG in various clinical stages of seminoma patients. Box plot illustration: bars within boxes denote median value. Upper and lower limits of the boxes denote upper (Q3) and lower (Q1) quartile limits, respectively. Whiskers are defined by values larger than Q3 or smaller than Q1, respectively, by at most 1.5 times the interquartile range. Stars denote mean values of groups. Logarithmic scale on y-axis. ULN: upper limit of norm. (b) Box plot illustration of median serum levels of bHCG in the various clinical stages of nonseminoma.
