	Grade 1	10 (17.9%)	1 (5.6%)
	Grade 2	2 (3.6%)	0

Grade 0: No TMD pain in the prior 6 months. Grade 1: Low disability - Low Intensity = CPI < 50, and less than 3 DP. Grade 2: Low Disability - High Intensity = CPI ≥ 50, and less than 3 DP. Grade 3: High Disability - Moderately Limiting = 3 to 4 DP, regardless of CPI. Grade 4: High Disability - Severely Limiting = 5 to 6 DP, regardless of CPI. CPI: Characteristic Pain Intensity. DP: Disability Points
Depression: Missing data: Mild OI: n = 12; moderate-severe OI: n = 5. Normal: < 0.535; Moderate: 0.535–1.105; Severe: < 1.105
Somatization: Missing data mild OI: n = 7; moderate-severe OI: n = 1. Normal: < 0.5; Moderate: 0.5–1.0; Severe: > 1.0
