Relation between wetness and interface type. The figure shows the box plots of wetness in obligate, non-obligate and crystal packing interfaces. The red line in the central of a box is the median; the upper and lower edges of a box are the 75% (v75) and 25% (v25) percentiles, respectively; and the two outer bars indicate the most extreme data points. All boxes are drawn without considering the outliers (red dots). A value is a outlier if it is larger than v75 + 1.5(v75 - v25) or smaller than v25 - 1.5(v75 - v25).
