Figure 1

Box-and-whisker plot of the mean intraocular pressure before and after surgery. The horizontal line within each box denotes the median value; the boxes extend from the 25^th to the 75^th percentiles of each group’s distribution of values; the vertical lines denote adjacent values (i.e., the most extreme values within the 1.5 interquartile range of the 25^th and 75^th percentiles of each group).
