This study included 47,359 cases with herpes zoster and 142,077 controls. 15.5% of cases compared to 12.1% of controls used statins.

Comment: The number needed to harm (i.e. cause 1 additional case of herpes zoster by taking a stating) in this study was 29. There is a significant risk of bias in this study, as people on statins might be more likely to visit the doctor than people not on statins.
