^**TMJD total = TMJD without pain + TMJD pain.

¹χ² test when compared TMJD with pain and control groups.

²χ² test when compared TMJD total and control groups.

^*[GC][GC], no presence of risk type.

^† $[\text{GC}][\overline{\text{GC}}]$, presence of only 1 risk type.

^‡ $[\overline{\text{GC}}][\overline{\text{GC}}]$, double presence of risk type.
