If used next to the names of the wrestlers, they may, in fact, not have held the title in the period indicated. If used next to the dates or places, either they are possibly wrong or the title changes are fictitious.

@
Order uncertain. Different titleholders may be known for the same year, for example, but it is not known who held the title before whom.
