A recent European case-control study suggested that statins increase the risk for polyneuropathy, a rare but serious neurologic condition. This risk was assessed in 272 patients with idiopathic polyneuropathy and 1,360 matched controls in the Intermountain Health Care electronic database. It was found that statin use before diagnosis was not significantly greater in patients than controls (odds ratio 1.30, 95% confidence interval 0.3 to 2.1, p = 0.27), nor were doses different between patients and controls.
