Stated aim for study | Quote from publication: "... to compare the efficacy of a subcutaneous fast‐acting analog (lispro) with continuous intravenous regular insulin (CIRI) in the treatment of pediatric DKA" | |
Notes | Study authors randomised episodes of DKA, not participants | |
Risk of bias | ||
Bias | Authors' judgement | Support for judgement |
Random sequence generation (selection bias) | Unclear risk | Quote from publication: "Of the 60 DKA episodes, 30 were randomised to treatment with a subcutaneous fast‐acting insulin analog (lispro) and the other 30 were randomised to treatment with CIRI" Comment: no detailed information |
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 | Comment: participants and personnel were probably unblinded |
Blinding of participants and personnel (performance bias) All‐cause mortality | Low risk | Comment: study personnel/participants probably not blinded, but outcome measurement unlikely to be influenced by the lack of blinding |
Blinding of participants and personnel (performance bias) Hypoglycaemic episodes | Unclear risk | Comment: study personnel/participants probably not blinded |
Blinding of participants and personnel (performance bias) Morbidity | Low risk | Comment: study personnel/participants probably not blinded, but outcome measurement unlikely to be influenced by the lack of blinding |
Blinding of outcome assessment (detection bias) Time to resolution of diabetic ketoacidosis | Unclear risk | Comment: no detailed information |
Blinding of outcome assessment (detection bias) All‐cause mortality | Low risk | Comment: no detailed information, but outcome measurement unlikely to be influenced by the lack of blinding |
Blinding of outcome assessment (detection bias) Morbidity | Low risk | Comment: no detailed information, but outcome measurement unlikely to be influenced by the lack of blinding |
Blinding of outcome assessment (detection bias) Hypoglycaemic episodes | Unclear risk | Comment: no detailed information |
Incomplete outcome data (attrition bias) Time to resolution of diabetic ketoacidosis | Low risk | Comment: reasons for dropouts explained |
Incomplete outcome data (attrition bias) All‐cause mortality | Unclear risk | Comment: DKA occurrences randomised, not participants (unclear which participants had only 1 DKA) |
Incomplete outcome data (attrition bias) Hypoglycaemic episodes | Unclear risk | Comment: DKA occurrences randomised, not participants (unclear which participants had only 1 DKA) |
Incomplete outcome data (attrition bias) Morbidity | Unclear risk | Comment: DKA occurrences randomised, not participants (unclear which participants had only 1 DKA) |
Selective reporting (reporting bias) | Unclear risk | Comment: possible outcome reporting bias for time to resolution of DKA (see Appendix 6) |
Other bias | Low risk | Comment: none detected |
