Risk Factors for an Iatrogenic Mallory-Weiss Tear Requiring Bleeding Control during a Screening Upper Endoscopy

Figure 3

Box and whisker plot of the numbers of previous upper endoscopies performed for bleeding control in iatrogenic Mallory-Weiss tear cases. The upper and lower parts of the whisker represent the observed maximum and minimum, respectively. The upper and lower edges of the boxes represent the 75th and 25th percentiles, respectively. The line inside the box represents the median value. Distributions of the numbers of previous upper endoscopies performed according to bleeding control in iatrogenic Mallory-Weiss tear cases. MWT, Mallory-Weiss tear.
