Isaacsohn 1998.
Methods | 10‐week washout period 12‐week before‐and‐after study |
|
Participants | 200 men and women aged 18‐75 years with documented primary hypercholesterolaemia LDL‐C ≥ 157.5 mg/dL (4.07 mmol/L) or ≥ 130 mg/dL (3.36 mmol/L) with documented CAD of ≥ 2 cardiovascular risk factors plasma TG ≤ 400 mg/dL (4.52 mmol/L) have a food rating score ≤ 15 Exclusion criteria: clinically active CVD, hypertension with alterations in diuretic or beta blocker therapy within 2 months of entry, uncontrolled diabetes mellitus or other endocrine abnormalities and uncontrolled hypothyroidism, ophthalmic abnormalities, cancer other than basil cell or squamous cell carcinoma, psychosis, hepatic dysfunction, weight 140% ideal body weight, statin hypersensitivity, significant GI tract disorders, child bearing potential homozygous FH, renal dysfunction, current use of other medications that would interfere with the trial, treatment with other hypolipidaemic drugs within 10 weeks of entry, drug or alcohol abuse, night shift workers, therapy with another investigational product within 30 d, other medical conditions which might interfere with the trial Cerivastatin 0.2 mg/d baseline TC: 6.94 mmol/L (268 mg/dL) Cerivastatin 0.2 mg/d baseline LDL‐C: 4.74 mmol/L (183 mg/dL) Cerivastatin 0.2 mg/d baseline HDL‐C: 1.24 mmol/L (48 mg/dL) Cerivastatin 0.2 mg/d baseline TG: 2.03 mmol/L (180 mg/dL) |
|
Interventions | Fluvastatin 20 mg/d for 0‐6 weeks evening dosing Fluvastatin 40 mg/d for 6‐12 weeks evening dosing Cerivastatin 0.2 mg/d for 0‐6 weeks evening dosing Cerivastatin 0.3 mg/d for 6‐12 weeks evening dosing |
|
Outcomes | Percentage change from baseline at 6 weeks of plasma TC, LDL‐C, HDL‐C, and TG | |
Source of funding | Novartis | |
Notes | Fluvastatin 20 mg/d for 0‐6 weeks Fluvastatin 40 mg/d for 6‐12 weeks Cerivastatin 0.3 mg/d for 6‐12 weeks Fluvastatin groups were not included in the efficacy analysis |

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 | High risk | [(200‐174)/200]*100 = 13% participants were not included in the efficacy analysis |
Incomplete outcome data (attrition bias) LDL cholesterol | High risk | [(200‐174)/200]*100 = 13% participants were not included in the efficacy analysis |
Incomplete outcome data (attrition bias) HDL cholesterol | High risk | [(200‐174)/200]*100 = 13% participants were not included in the efficacy analysis |
Incomplete outcome data (attrition bias) Triglycerides | High risk | [(200‐174)/200]*100 = 13% participants were not included in the efficacy analysis |
Selective reporting (reporting bias) | Low risk | LDL‐C outcome was reported |
Other bias | High risk | Novartis funded the trial, data may support bias against cerivastatin |
