Risk of bias | ||
Bias | Authors' judgement | Support for judgement |
Random sequence generation (selection bias) | Unclear risk | Method of random sequence generation was not reported |
Allocation concealment (selection bias) | Unclear risk | Method of allocation concealment was not reported |
Blinding of participants and personnel (performance bias) All outcomes | Low risk | Lipid parameter measurements unlikely influenced by lack of sufficient blinding |
Blinding of outcome assessment (detection bias) LDL‐C | Low risk | LDL‐C was measured in a remote laboratory |
Blinding of outcome assessment (detection bias) WDAE | Unclear risk | Blinding method was not described |
Incomplete outcome data (attrition bias) Total cholesterol | Low risk | All participants were included in the efficacy analysis |
Incomplete outcome data (attrition bias) LDL cholesterol | Low risk | All participants were included in the efficacy analysis |
Incomplete outcome data (attrition bias) HDL cholesterol | Low risk | All participants were included in the efficacy analysis |
Incomplete outcome data (attrition bias) Triglycerides | Low risk | All participants were included in the efficacy analysis |
Selective reporting (reporting bias) | Low risk | LDL‐C outcome was reported |
Other bias | Unclear risk | Source of funding not reported |
