^aMultiple-response questions
All the classifications of the groups in Tables 1–4, excluding ‘marital status’ and ‘sphere of psychotraumatic situation’, were used as categorical independent valuables. The valuables extracted were listed; no variable was extracted in the demographic section. The odds were expressed against the odds of the group with possibly without PTSD (Total-I <34 and Total-C <40, n = 77, approx. 40 %; low score)/the group possibly with PTSD (either Total-I ≥34 or Total-C ≥40. n = 110, approx. 60 %; high score). That is, the odds values >1 and <1 represent the likelihood of being a low score and a high score, respectively
