Risk of bias | ||
Bias | Authors' judgement | Support for judgement |
Random sequence generation (selection bias) | High risk | Controlled before‐and‐after design |
Allocation concealment (selection bias) | High risk | Controlled before‐and‐after design |
Blinding of participants and personnel (performance bias) All outcomes | Low risk | Lipid parameter measurements unlikely influenced by lack of blinding |
Blinding of outcome assessment (detection bias) LDL‐C | Low risk | Lipid parameters were measured in a remote laboratory |
Blinding of outcome assessment (detection bias) WDAE | High risk | No comparison possible |
Incomplete outcome data (attrition bias) Total cholesterol | Low risk | [(71‐65)/71]*100 = 8.5% participants were not included in the efficacy analysis for the cerivastatin 0.05 mg/d group for total cholesterol [(79‐73)/79]*100 = 7.6% participants were not included in the efficacy analysis for the cerivastatin 0.1 mg/d group for total cholesterol [(70‐67)/70]*100 = 4.3% participants were not included in the efficacy analysis for the cerivastatin 0.15 mg/d group for total cholesterol [(74‐70)/74]*100 = 5.4% participants were not included in the efficacy analysis for the cerivastatin 0.2 mg/d group for total cholesterol |
Incomplete outcome data (attrition bias) LDL cholesterol | High risk | [(71‐61)/71]*100 = 14.1% participants were not included in the efficacy analysis for the cerivastatin 0.05 mg/d group [(79‐66)/79]*100 = 16.5% participants were not included in the efficacy analysis for the cerivastatin 0.1 mg/d group [(70‐63)/70]*100 = 10.0% participants were not included in the efficacy analysis for the cerivastatin 0.15 mg/d group [(74‐64)/74]*100 = 13.5% participants were not included in the efficacy analysis for the cerivastatin 0.2 mg/d group [(294‐254)/294]*100 = 13.6% participants were not included in the efficacy analysis for all doses |
Incomplete outcome data (attrition bias) HDL cholesterol | Low risk | [(71‐65)/71]*100 = 8.5% participants were not included in the efficacy analysis for the cerivastatin 0.05 mg/d group [(79‐73)/79]*100 = 7.6% participants were not included in the efficacy analysis for the cerivastatin 0.1 mg/d group [(70‐67)/70]*100 = 4.3% participants were not included in the efficacy analysis for the cerivastatin 0.15 mg/d group [(74‐70)/74]*100 = 5.4% participants were not included in the efficacy analysis for the cerivastatin 0.2 mg/d group |
Incomplete outcome data (attrition bias) Triglycerides | Low risk | [(71‐63)/71]*100 = 11.3% participants were not included in the efficacy analysis for the cerivastatin 0.05 mg/d group [(79‐70)/79]*100 = 8.9% participants were not included in the efficacy analysis for the cerivastatin 0.1 mg/d group [(70‐65)/70]*100 = 7.1% participants were not included in the efficacy analysis for the cerivastatin 0.15 mg/d group [(74‐69)/74]*100 = 6.8% participants were not included in the efficacy analysis for the cerivastatin 0.2 mg/d group |
Selective reporting (reporting bias) | Low risk | LDL‐C outcome was reported |
