Low risk of bias |
The randomisation schedule for treatment assignments was prepared by centre on a 1:1 basis. A randomisation list was provided to each centre (pharmacy department or appropriate study personal but not to investigator blinded to the study). There were no relevant baseline imbalances. |
Low risk of bias |
Single‐blind trial design: the investigator responsible for insulin dosage adjustment was blinded to the treatment allocated to the participant and was not involved in any aspect relating to study supplies. The study coordinator and the participant were aware of the treatment allocation. The primary efficacy analysis was carried out with a modified intention‐to‐treat population (ITT), which consisted of all randomised patients with at least one dose of study medication. All secondary efficacy variables were also analysed on an ITT basis. |
Low risk of bias |
Withdrawals and reasons for withdrawal were documented, did not differ substantially between intervention groups and did not appear to be related to health status. The primary efficacy analysis was carried out with a modified intention‐to‐treat population (ITT), which consisted of all randomised patients with at least one dose of study medication. All secondary efficacy variables were also analysed on an ITT basis. The safety population consisted of all randomised participants who received at least one dose of study medication. |
Low risk of bias |
Open‐label design with outcome measure unlikely influenced by lack of blinding. |
Low risk of bias |
Data from full clinical study report. Only one measurement and result provided for the time point selected by review authors. |
Low risk of bias |
No risk of bias identified. |

Low risk of bias |
A 1:1 randomisation schedule was generated by the sponsor. This schedule paired sequential numbers with treatment codes allocated at random. The schedule was prepared by centre on a 1:1 basis. An independent agency was used for central telephone randomisation. There were no relevant baseline imbalances. |
Low risk of bias |
Open‐label trial design. A modified intention‐to‐treat analysis was applied (participants with at least one measurement after baseline). |
Low risk of bias |
Withdrawals and reasons for withdrawal were documented, did not differ substantially between intervention groups and did not appear to be related to health status. Modified intention‐to‐treat analysis set was used (efficacy was analysed using those intention‐to‐treat (ITT) participants for whom both a pre‐treatment and an on‐treatment value were available, with the exception of hypoglycaemia, for which the entire ITT population was analysed). |

| Ratner 2000 |
Low risk of bias |
The randomisation schedule was stratified according to centre and pre‐randomisation basal insulin regimen of once versus twice daily. Forty randomisation numbers were allocated to each basal insulin regimen for each centre. To ensure a balanced number of participants for each treatment group the randomisation schedule was generated using block sizes of 4. An independent agency was used for central telephone randomisation. There were no relevant baseline imbalances. |
Low risk of bias |
Open‐label trial design. The modified intention‐to‐treat (ITT) population was defined as all participants randomised and treated and having both a pretreatment and a during‐treatment value. |
Low risk of bias |
Withdrawals and reasons for withdrawal were documented, did not differ substantially between intervention groups and did not appear to be related to health status. The modified intention‐to‐treat (ITT) population was defined as all participants randomised and treated and having both a pre‐treatment and a during‐treatment value. An ITT analysis was performed for all variables. Participants with missing baseline values or no value during treatment were excluded from the statistical analysis of the variable in question. |

| Chase 2008 |
Low risk of bias |
Two randomisation schedules with a 1:1 randomisation ratio, one for males another for females, were generated by the sponsor. At the point of randomisation both the investigator/study coordinator and the participant were blinded to the treatment allocation (to randomisation). The randomisation schedule was stored with the randomisation code administrator at Aventis Pharmaceuticals, Bridgewater, NJ. There were no relevant baseline imbalances. |
Low risk of bias |
Open‐label trial design. Modified intention‐to‐treat analysis set was used (participants taking at least one dose of study medication with a baseline measurement and at least one follow‐up measure; the safety population consisted of all randomised participants who received at least one dose of study medication). |

Low risk of bias |
Participants were centrally randomised (utilising permuted block randomisation schedule) via Interactive Voice Response System (IVRS) at a 1:1 ratio to one of the two treatment groups. There were no relevant baseline imbalances. |
Low risk of bias |
Open‐label trial design. A modified intention‐to‐treat analysis was applied (all randomised participants exposed to at least one dose of trial product). |
Low risk of bias |
Withdrawals and reasons for withdrawal were documented, did not differ substantially between intervention groups and did not appear to be related to health status. The efficacy population consisted of all randomised patients who received at least one dose of the study medication (modified intent‐to‐treat [mITT] population). |

Low risk of bias |
Withdrawals and reasons for withdrawal were documented, did not differ substantially between intervention groups and did not appear to be related to health status. The modified intention‐to‐treat (ITT) population was defined as all participants randomised and treated. The safety population compromised all participants who were randomised and received study medication. Efficacy was analysed using those ITT participants for whom both a pre‐treatment and an on‐treatment value were available. |
