Figure 3. Box-whisker analyses of log-transformed HE4 concentration in 39 clinical urine samples.

Figure 3

For all three methods, the logarithm-transformed HE4 concentrations for the majority (i.e., the “box” part of the box-whisker plot) of cancer urine samples (n=19) was greater than that of normal urine samples (n=20). The minimum, first quartile, median, third quartile, and maximum of the logarithm-transformed HE4 concentrations were −6.215, −1.623, 0.631, 0.572, 2.729, and 5.624 for the microplate method, 4.755, 5.188, 6.101, 5.999, 6.751, 7.965 for the cell phone method, and 4.550, 5.254, 5.844, 6.095, 6.865, 8.511 for the CCD method. A few outliers were observed for the logarithm-transformed HE4 concentrations measured by cell phone and CCD methods.
