Box-and-whisker plots. PSA quantitative values were plotted according to the intensity of the red bands in PSA SPOT tests among all samples (a) and samples in which the PSA value was between 0 and 10 ng/mL (b). The horizontal line within each box represents the median, the ends of the box represent the 25th and 75th percentiles, the whiskers extend from the ends of the box to the minimum and maximum, and the individual dots beyond the whiskers represent outliers
