Notes	—
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	High risk	Seems quasi‐RCT, conflicting information about randomisation between abstract (random table) and full text (allocated according to the order of visit).
Allocation concealment (selection bias)	High risk	Seems quasi‐RCT, conflicting information about randomisation between abstract (random table) and full text (allocated according to the order of visit).
Patient's baseline characteristics (selection bias)	Low risk	The author declared that there are no statistical differences regarding age and gender (P > 0.05) at baseline.
Patient's baseline outcomes (selection bias)	Unclear risk	Nothing reported about baseline outcome.
Incomplete outcome data (attrition bias)	Unclear risk	Looks like they only report the number of patients analysed. No report about any lost.
Blinding of participants and personnel (performance bias) and of outcome assessors (detection bias)	Low risk	Hypoglycaemia events were objectively measured (the author measured the fasting blood‐glucose and blood‐glucose 2 hours after meal).
Selective reporting (reporting bias)	Unclear risk	No registered or published protocol. Results match methods.
Risk of contamination (other bias)	Unclear risk	Patients randomised. Nurses were working with usual doctors so the latter might have changed their approach with their control patients.
Other bias	Low risk	No evidence of other risk of bias.
