You seem to be under the impression that a study like this gives a hard "yes/no" answer as to whether some hypothesis is true. That is not the case, nor is it ever the case with most studies like these. Instead, you need to do some sort of statistical hypothesis test.

As other comments have pointed out, once you start testing multiple hypothesis on the same dataset, you cannot apply the same significance threshold that you would if you had just begun with a single hypothesis before observing the data. Instead, you need to apply some sort of correction that takes into account the number of hypothesis being tested:
