As discussed in the literature review in section 2.8.1 and shown in Figure 4-5, the p-value of <0.0001 indicates that at least one median is statistically different. The indication from the mean rank, shown above, is the 1 to 30-day group has the shortest time from the call to recovery, while the 61 to 90-day group has the longest call to recovery. To validate this indication, three pairwise Mann-Whitney comparisons were preformed between all groups.
The first Mann-Whitney comparison, shown in Figure 4-6, is a comparison between the 1 to 30 day group, and the 31 to 60-day group. The second Mann-Whitney comparison, shown in Figure 4-7, is a comparison between the 1- to 30-day group to the 61 to 90 day group. The third Mann-Whitney comparison,
