a
, Mann–Whitney.
b
, t-test.
c
, Chi-square. ISI, insomnia severity index; SRI, stress response inventory; TMD, temporomandibular disorder; T, tension; Ag, aggression; S, somatization; An, anger; D, depression; F, fatigue; Fr, frustration. A total ISI score of 0–7 indicates grade ‘0’, a total ISI score of 8–14 indicates grade ‘1’, a total ISI score of 15–21 indicates grade ‘2’, a total ISI score of 22–28 indicates grade ‘3’.
