Among people with type 2 diabetes starting insulin, rosuvastatin appears to offer the strongest protection against heart attacks, strokes, or heart-related death compared to other statins like atorvastatin or simvastatin.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
A meta-analysis of RCTs could determine whether rosuvastatin consistently provides superior MACE reduction compared to other statins in insulin-treated type 2 diabetes, controlling for dose and baseline risk.
A systematic review and meta-analysis of all randomized trials comparing rosuvastatin to atorvastatin, simvastatin, or pravastatin in adults with type 2 diabetes initiating insulin, with MACE as primary endpoint, stratified by statin dose and baseline LDL-C, including trials with ≥500 participants and ≥3-year follow-up.
An RCT could determine whether rosuvastatin directly causes greater MACE reduction than other statins in insulin-initiating patients, independent of selection bias.
A four-arm, double-blind RCT of 2000 adults with type 2 diabetes newly starting insulin, randomized to rosuvastatin 10mg, atorvastatin 20mg, simvastatin 40mg, or placebo, with MACE as primary endpoint over 5 years, and LDL-C, HbA1c, and safety monitored quarterly.
A prospective cohort could confirm whether rosuvastatin users have lower MACE rates than users of other statins after adjusting for dose, duration, and baseline risk factors.
A prospective cohort of 5000 adults with type 2 diabetes initiating insulin, stratified by statin type (rosuvastatin, atorvastatin, simvastatin, pravastatin), with annual MACE surveillance, statin dose, LDL-C, and HbA1c tracked for 5 years, adjusting for baseline comorbidities and lifestyle.
A case-control study could test whether individuals who experienced MACE were less likely to have used rosuvastatin compared to other statins.
A case-control study comparing 800 adults with type 2 diabetes who had MACE within 5 years of insulin initiation (cases) to 800 matched controls without MACE, assessing prior statin type, dose, and duration before insulin start.
A cross-sectional analysis could show whether rosuvastatin use correlates with lower MACE prevalence at a single time point after insulin initiation, but cannot establish causality.
A cross-sectional analysis of 10,000 adults with type 2 diabetes who started insulin 1–5 years prior, comparing prevalence of MACE among users of rosuvastatin, atorvastatin, simvastatin, and pravastatin, adjusting for age and baseline HbA1c.
