Is there a link between religious fractionalisation and civil war?

According to the Collier-Hoeffler model of Civil War Onset, on a rating between 0 and 100, the average amount of religious fractionalisation in countries that do not experience civil war stood at 35.98, and in countries that did at 37.70, a difference of 1.72.

In comparison, the difference in ethnic fractionalisation was rated at 13.99.

Is this small difference in religious fractionalisation likely to have started civil wars?
