Significance
In the other study, there were 1389 data-points, each having a value. 125 of the values in the other study had a value larger than the largest value in my study.

My study had 38 data-points. If I'm correct here, if the probability to get a certain value in both studies was the same, I would expect to have (125/1389)*38=3.41973 data-points with a larger value than the largest value in my study. Given the fact that I have none, is it statistically significant? E.g. is there more than 5% chance that this was not a random co-incidence?
