Methods Wash‐out was not required because participants were excluded if they received lipid‐lowering drugs within 3 months of the study
3‐Month randomised double‐blind placebo‐controlled trial
Participants 77 men and women from USA with diabetes or at risk of diabetes aged 51 years (21‐80); BMI 29.65
Exclusion criteria: cardiac arrhythmia, congestive heart failure, uncontrolled HTN, recent stroke, chronic renal disease, severe dyslipidaemia or other serious chronic disease requiring active treatment, participants taking glucocorticoids, antineoplastic agents, psychoactive drugs and bronchodilators, type 2 diabetes and at risk of type 2 diabetes groups combined
Placebo:
Baseline TC: 5.48 mmol/L (212 mg/dL)
 Baseline LDL‐C: 3.28 mmol/L (127 mg/dL)
 Baseline HDL‐C: 1.61 mmol/L (62 mg/dL)
 Baseline TG: 1.25 mmol/L (111 mg/dL)
Atorvastatin:
Baseline TC: 5.16 mmol/L (200 mg/dL)
 Baseline LDL‐C: 3.10 mmol/L (120 mg/dL)
 Baseline HDL‐C: 1.51 mmol/L (58 mg/dL)
 Baseline TG: 1.29 mmol/L (114 mg/dL)
Interventions Placebo
Atorvastatin 20 mg/d
Outcomes Per cent change from baseline at 12 weeks of serum TC, LDL‐C, HDL‐C and TG
Notes No WDAEs were reported
SDs were imputed
Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Unclear risk No information about sequence generation was provided to permit judgement of 'yes' or 'no'
Allocation concealment (selection bias) Unclear risk No information about sequence generation was provided to permit judgement of 'yes' or 'no'
Blinding (performance bias and detection bias) 
 All outcomes Low risk "Double‐blind fashion"
Incomplete outcome data (attrition bias) 
 All outcomes High risk 10/77 participants were not analysed
19% of participants were excluded from the efficacy analysis
Risk of bias is quite high
Selective reporting (reporting bias) High risk All lipid parameters were measured; WDAEs were not reported
Other bias High risk Pfizer partially funded the study; data may support bias for the drug
