Abbreviations: aOR, adjusted odds ratio; CI, confidence interval.
The model was adjusted for the following confounders: age, male sex, current smoking, chronic lower respiratory diseases, malignant neoplasms of the lung, body temperature during triage, respiratory rate during triage, Glasgow Coma Scale, blood paraquat concentration (ppm), blood creatinine level (mg/dL), cyclophosphamide treatment, intubation, signed Do Not Resuscitate, and liberal oxygen therapy.
