Pirateplot of the intensity of pain in patients with chronic pain syndrome as measured by items 24 and 25 of the Bodily and Emotional Perception of Pain. The pirateplot reports the raw data as points (with noise [jitter] added horizontally to reduce overlap among points with similar value); a vertical bar shows the central tendency in the data within a rectangle, with its extremes indicating the 95% confidence interval of the mean. A smoothed density of the distribution of the data is also depicted.
