- 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
- ECG = Electrocardiogram
- a if oxygen satuartion < 90% (60 patients)
- b if patient rated pain according to NRS > 3 (1234 patients)
- c if patient reported nausea (540 patients)
