  1. No information found taken as sign/symptom not recorded, rather than the patient was not experiencing this sign/symptom. P values are reported to two decimal places, except where the third place gives additional information as advised: P values >0.01 should be reported to two decimal places, those between 0.01 and 0.001 to three decimal places; P values smaller than 0.001 should be reported as P < 0.001 (The New England Journal of Medicine, https://www.nejm.org/author-center/new-manuscripts, accessed 30.10.2019) [27]
  2. RR respiratory rate, sats saturation percentage, HR heart rate, SBP systolic blood pressure, Hb haemoglobin
  3. aUrine passed in the toilet was counted as recorded
  4. bClinical parameters were not listed on the standard observation chart (control arm) but data were found in the patients’ progress notes and/or other documents
