Notes
Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Quote from publication: "The study patients were randomised in emergency department following a computer generated randomisation table in two groups"
Allocation concealment (selection bias) Unclear risk Comment: no detailed information
Blinding of participants and personnel (performance bias) 
 Time to resolution of diabetic ketoacidosis High risk Quote from publication: "In this prospective, randomised and open trial ..."
Comment: participants and personnel were unblinded (open trial)
Blinding of participants and personnel (performance bias) 
 All‐cause mortality Low risk Quote from publication: "In this prospective, randomised and open trial ..."
Comment: participants and study personnel not blinded, but outcome measurement not likely to be influenced by the lack of blinding
Blinding of participants and personnel (performance bias) 
 Hypoglycaemic episodes Unclear risk Quote from publication: "In this prospective, randomised and open trial ..."
Comment: participants and personnel were unblinded (open trial)
