While statins slightly increase the chance of being diagnosed with diabetes, the actual number of extra cases is very small—about 1 extra case per 100 people per year with strong doses—and most of these diagnoses happen because doctors test blood sugar more often, not because statins cause widespread diabetes.

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.
This meta-analysis itself provides the definitive quantification of absolute excess risk across trials with varying testing protocols, establishing that detection frequency modulates observed incidence.
This study is already the ideal systematic review: comparing absolute diabetes rates across 19 trials with differing HbA1c testing frequencies and isolating the effect of testing intensity on observed excess cases.
An RCT could isolate whether increased HbA1c testing frequency alone increases diabetes diagnosis rates without statin exposure.
A double-blind RCT of 8,000 adults aged 50–70 without diabetes, randomized to quarterly HbA1c testing vs. annual testing, with no statin use, measuring diabetes diagnosis rates over 4 years.
Could determine whether populations with routine HbA1c screening have higher diabetes incidence rates independent of statin use.
A prospective cohort comparing diabetes incidence over 5 years in two matched populations: one with annual HbA1c screening and one without, both without statin use, adjusting for age, BMI, and family history.
Could compare prior testing frequency between statin users diagnosed with diabetes and those not diagnosed.
A case-control study of 1,200 statin users diagnosed with diabetes and 2,400 not diagnosed, comparing number of HbA1c and glucose tests in the 2 years before diagnosis.
Could show correlation between number of prior glucose tests and current diabetes diagnosis status, but cannot establish causality.
A cross-sectional survey of 10,000 statin users, asking number of HbA1c tests in prior 3 years and current diabetes status.
