Figure 4
Progression-free survival of PC, PCF10 and PCF20 patients by fIGF-1 quartile. The central box represents the values from the lower to upper quartile (25–75 percentile). In the box plots, the middle line represents the median. A line extends from the minimum to the maximum value, excluding ‘outside’ values that are displayed as separate points. An outside value is defined as a value that is smaller than the lower quartile minus 1.5 times the interquartile range, or larger than the upper quartile plus 1.5 times the interquartile range (inner fences). These values are plotted with a square marker.
