Who is the patient with resistant myofascial temporomandibular disorders pain? A somatosensory, psychosocial, and genetic characterization

Table 5 OPLS-DA model of variables discriminating temporomandibular disorders myofascial pain patients resistant to treatment (TMD-R) from patients with a successful treatment outcome (TMD-S). Twelve variables significantly discriminated between groups and had a VIP-value > 1.0 and a p(corr) > 0.4. WUR and PPT had a negative p(corr) and were lower in TMD-R
