What is mainly uncovered by Analyzing Causes? Anicca or Dukkha or Anatta?

The Abhidhamma Commentary says: - Anicca-characteristic is hidden due to "Non-contemplation of the **Rising and falling**." - Dukkha-characteristic is hidden due to "Shifting of the **Postures**." - Anatta-characteristic is hidden due to "Non-contemplation of the **Analysis of Different Elements**." Where does the causality fit in this? Which characteristic is (mainly) uncovered by the "Contemplation of Dependent-origination?" Obviously it uncovers all the three in some way. I'm here asking about it's main contribution.
