Myasthenia gravis following statin therapy: evidence from target trial emulation and self-controlled case series study.

ABSTRACT: Several international pharmacovigilance agencies have issued warnings regarding the potential risk of myasthenia gravis (MG) following statin therapy. Our study investigated this association using population-based electronic health records in Hong Kong. We conducted a sequence of target trial emulation (TTE) for interpersonal comparison and a self-controlled case series (SCCS) study for intrapersonal comparison. In the TTE for MG onset, the incidence rates (per 100,000 person-years) and adjusted HRs were 51.91(31.80, 84.74)[HR:6.11 (3.73, 10.01)] in month 1, 16.27(9.81, 26.99)[HR:1.92(1.15, 3.19) in months 2-4, and 15.27(9.05, 25.79)[HR:1.80(1.06, 3.04)] in months 5-7. For risk of exacerbation, the adjusted HRs were 10.69(5.48, 20.84) in month 1, 1.50(0.55, 4.06) in months 2-4, and 2.79(1.
