Study characteristics
Methods Study design: Historically controlled trial
Study grouping:
Method: 4 to 6‐week washout period; 8‐week before‐and‐after study with evening dosing; HDL cholesterol data weres not included in the efficacy analysis because the calculated percentage change versus given percentage change was greater than 10%.
Participants Baseline Characteristics
Pitavastatin 2 mg/day
  • n: 313

  • Age (years): 57.4

  • Males (n): 106

  • Females (n): 207

  • Total cholesterol: 290 mg/dL (7.50 mmol/L)

  • LDL cholesterol: 201.7 mg/dL (5.22 mmol/L)

  • HDL cholesterol: 55.9 mg/dL (1.45 mmol/L)

  • Triglycerides: 175 mg/dL (1.98 mmol/L)


Included criteria: Serum total cholesterol value of 220 mg/dL (5.69 mmol/L) or more. Ages: 20‐75 years old.
Excluded criteria: Patients with poor control of diabetes and patients with severe hypertension, patients with severe hepatopathy, renal impairment, myocardial infarction and cerebrovascular disorder attack (within 3 months after the attack) and patients with heart failure, women who are breastfeeding, pregnant women or women who desire pregnancy, patients with a history of drug hypersensitivity or a history of serious side effects, other patients who were judged inappropriate as subjects of this trial by the investigators, no consent of trial participation

Notes  
Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) High risk Judgement Comment: Controlled before‐and‐after design
Allocation concealment (selection bias) High risk Judgement Comment: Controlled before‐and‐after design
Blinding of participants and personnel (performance bias)
All outcomes Low risk Judgement Comment: Lipid parameter measurements unlikely to be influenced by lack of blinding
Blinding of outcome assessment (detection bias)
All outcomes Low risk Judgement Comment: Lipid parameters were measured in a remote laboratory.
Selective reporting (reporting bias) Low risk Judgement Comment: LDL‐cholesterol outcome was reported.
Other bias Unclear risk Judgement Comment: Source of funding was not reported.
Incomplete outcome data (attrition bias) Total cholesterol Low risk [(313 ‐ 295)/313]*100 = 5.8% were not included in the efficacy analysis for total cholesterol at 4 weeks; [(313 ‐ 277)/313]*100 = 11.5% were not included in the efficacy analysis for total cholesterol at 8 weeks.
Incomplete outcome data (attrition bias) LDL cholesterol) Unclear risk [(313 ‐ 289)/313]*100 = 7.7% were not included in the efficacy analysis for LDL cholesterol at 4 weeks; [(313 ‐ 268)/313]*100 = 14.4% were not included in the efficacy analysis for LDL cholesterol at 8 weeks.
Incomplete outcome data (attrition bias) HDL cholesterol High risk No data included in the efficacy analysis because the data differed by more than 10% between given and calculated values
Incomplete outcome data (attrition bias) Triglycerides High risk [(313 ‐ 138)/313]*100 = 55.9% were not included in the efficacy analysis for triglycerides at 4 weeks; [(313 ‐ 133)/313]*100 = 57.5% were not included in the efficacy analysis for triglycerides at 8 weeks.
Blinding of outcome assessment (detection bias)WDAEs High risk No comparison possible
Selective reporting (reporting bias) for WDAEs High risk No WDAE outcome reported
