  1. Univariate logistic regression analyses. Analyses on treatment with oxygen, sublingual glyceral trinitrate, oxycodone and odansetron excuted on subgroups based on signs and symptoms as stated below
  2. ECG = Electrocardiogram
  3. a if oxygen satuartion < 90% (60 patients)
  4. b if patient rated pain according to NRS > 3 (1234 patients)
  5. c if patient reported nausea (540 patients)
