Methods | 4‐week placebo run‐in period 6‐week RCT Allocations via block randomisation in groups of 6 |
|
Participants | 32 men and women with primary hypercholesterolaemia aged 18‐75 years. Average LDL‐C measured during diet‐stabilisation and placebo run‐in stage had to be > 160 mg/dL (4.14 mmol/L) with definite personal history of coronary heart disease and each measurement had to be not > ± 12% from the average (> 130 mg/dL (3.36 mmol/L) for participants with > 2 risk factors for CAD or CVD) fasting plasma TG below 350 mg/dL (3.95 mmol/L) for all participants, consent received from all participants During period A, included participants had to have diet satisfied by dietician (i.e. meeting dietician recommendations). Compliance rate to placebo during period A was between 80%‐120%; 26 did not finish placebo run‐in period A; 47 participants were randomised Exclusion criteria: women of childbearing age but not on IUD or OCP; pregnant or breastfeeding; participants with history of MI, unstable angina, stroke, TIA, and uncontrolled hypertension within 3 months of starting trial; CABG or PCI within 6 months of starting trial. Regardless of whether they're on treatment or not, if fasting glucose is > 140 mg/dL or having other endocrine disease, or someone with systolic BP > 180 mmHg or diastolic BP > 110 mmHg; clinically known to have cataract or malignant tumour or psychiatric condition or chronic seizures or “homogenous hypercholesterolaemia” (homogenous family history?). BMI > 30, SCr > 2 mg/dL, AST/ALT/amylase > 1.5 ULN or CK > 3, chronic or acute infection, if require regular care visits or compliance expected to be affected, if alcohol or drug abuse in medical history (> 14 drinks/week for alcohol use), if occupational shift work requiring working overnight, bodybuilders or weightlifters, people on other cholesterol medications are excluded; if they stop the statin 4 weeks before or fibrates 8 weeks before or probucol 6 months before, then they can be included in the trial; people with sensitivities to statins, anyone involved with any other trial within 30 d of starting this trial Placebo baseline TC: 6.42 mmol/L (248 mg/dL) Placebo baseline LDL‐C: 4.36 mmol/L (169 mg/dL) Placebo baseline HDL‐C: 1.26 mmol/L (49 mg/dL) Placebo baseline TG: 1.77 mmol/L (157 mg/dL) Cerivastatin 0.1 mg/d baseline TC: 6.97 mmol/L (270 mg/dL) Cerivastatin 0.1 mg/d baseline LDL‐C: 4.86 mmol/L (188 mg/dL) Cerivastatin 0.1 mg/d baseline HDL‐C: 1.19 mmol/L (46 mg/dL) Cerivastatin 0.1 mg/d baseline TG: 2.01 mmol/L (178 mg/dL) Cerivastatin 0.3 mg/d baseline TC: 6.77 mmol/L (262 mg/dL) Cerivastatin 0.3 mg/d baseline LDL‐C: 4.59 mmol/L (177 mg/dL) Cerivastatin 0.3 mg/d baseline HDL‐C: 1.31 mmol/L (51 mg/dL) Cerivastatin 0.3 mg/d baseline TG: 1.90 mmol/L (168 mg/dL) |

|
Outcomes | Percentage change from baseline at 4‐6 weeks of blood TC, LDL‐C, HDL‐C, and TG | |

Risk of bias | ||
Bias | Authors' judgement | Support for judgement |
Random sequence generation (selection bias) | Unclear risk | Random sequence generation was not reported |
Allocation concealment (selection bias) | Unclear risk | 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 | Lipid parameters were measured in a remote laboratory |
Blinding of outcome assessment (detection bias) WDAE | High risk | WDAEs were not reported |
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 was not reported |
