Figure 1. Impact of SLCO1B1 rs4149056 genotype on risk of statin-induced myopathy and rhabdomyolysis in simvastatin, lovastatin, and atorvastatin users.
Odds ratios (ORs) and 95% confidence intervals for risk of statin-induced myopathy and rhabdomyolysis with rs4149056 genotype are shown by statin type. ORs for TC and CC genotype are compared to TT genotype. In the entire cohort of statin users, a significantly increased risk of statin-induced myopathy and rhabdomyolysis was observed in individuals with the CC genotype. In the subset of simvastatin and lovastatin users, CC genotype was associated with significantly increased risk of statin-induced myopathy and rhabdomyolysis. In addition, TC genotype conferred a significantly increased risk in simvastatin users. In contrast, for atorvastatin users, no statistically significant risk for statin-induced myopathy and rhabdomyolysis was identified.
