Als er 2 verschillende treatments worden vergeleken met elkaar kan je niet aan de hand van het verschil zeggen of het significant is. Als het verschil negatief is wil dit zeggen dat het 2e gegeven element beter is dan het 1e gegeven element. Als het verschil positief is wil dit zeggen dat het 1e element beter is dan het 2e.
Bv: H:0-E:0 => verschil -0.471
Dit wilt zeggen dat E beter is dan H. Of dit wel of niet significant beter is kan je pas zeggen door naar de p-waarde te kijken. Hier is de p-waarde 0.041, wat kleiner is dan 0.05 waardoor dit een significant verschil is.

F:1-E:0 => Verschil 0.008
Dit wilt zeggen dat treatment F beter is dan treatment E. Dit verschil is echter enorm klein, en als je naar de p-waarde ziet: 1, kan je zeggen dat dit slechts door het toeval zo is.

E:1-E:0 => Verschil -0.171
treatment E is hier beter bij vrouwen dan bij mannen. Dit kan je zien aan het minteken. De p-waarde is 0.846, en is groter dan 5%, dus het verschil is niet significant.
