After printing the Class Dependencies Report (Reports->Dependency->Class Dependencies), we see some headers, with relating numbers that might be confusing as to what exactly they mean. The Dependency Browser can be very useful in seeing the actual dependencies and what they relate to, so I am going to use the Java sample project (getopt) that comes with Understand, the csv file, and the Dependency Browser, to explain the dependencies shown. 
The Dependency Browser shows the Class: GetoptDemo on the left side, and it depends on Getopt and LongOpt (shown on the right of the Dependency Browser, and also in the ‘To Class’ column of the csv file).  In Getopt there are 13 References, and LongOpt there are 12 References.  Both of which are shown in the References column and on the right side of the Dependency Browser.

The ‘To Entities’ column shows the specific entities that depend on GetoptDemo.  So, expanding the tree on the right side of the Dependency Browser shows the 8 entities that GetoptDemo depends on in Getopt, and the 6 entities that GetoptDemo depends on in LongOpt.

dependenciesFromEntities

The From Entities is the number of entities in GetoptDemo that have dependencies.  By going to the method GetoptDemo on the left side of the Dependency Browser, and expanding the dependencies on that method in the right side of the Browser, we see that there is 1 dependency in Getopt, and 1 dependency in LongOpt.

Now, continue to look at the ‘From Entities’ on the left side of the Dependency Browser by looking at Variable: g, expand the tree on the right and see that it depends on Getopt.  Which brings the number of From Entities for Getopt from 1 to 2.

Finally, look at the last entity for GetoptDemo on the left, ‘Variable: longopts’, expand the tree on the right and see that it Depends on LongOpt, which brings the number of From Entities from 1 to 2 for LongOpt.

Hopefully this sample clarifies the Class Dependencies csv report.
