I was looking at Boons, and noticed some Boons increase Crowd Control Ability. Example: the WoD Boon that gives +10% Control Ability.
As a TR it would make my smoke bomb, and other control effects last longer, but according the wiki Combat Advantage is classified as a control ability as well. It is the first thing listed under Crowd Control "Combat Advantage - Gives a damage bonus, usually dependent on placement of players or enemies, but can also be granted by certain powers." (

It looks like the Wiki entry is just talking about "Crowd Control" in general, and not the actual Control stat...since a lot of those effect listed wouldn't really apply.
If you need a good reference, look at the tooltip for Transcendent Elven Battle. Those are the effects that Control Bonus/Resist generally apply to.
