Box Plot from Scientific Research

Box-and-whisker plots representing the change scores (left y axis) for each of the surgical (month 1 minus 0), rehab-only (month 3 minus 1), DBS + rehab (month 8-12 (maximum achieved) minus 4), rehab carryover (month '+2' minus month 8-12) and long-term follow-up (month '+10' minus 8-12) trial phases. A score of zero signifies no change in impairment for that phase, with higher values reflecting improvement (that is, decreased impairment). The overlaid line plot represents the cumulative median change (right y axis) across the trial (n = 12 independent participants; two-sided Wilcoxon signed-rank test; * P = 0.004; ** P < 0.001).
