LRRK2 and Parkinson disease: In this smaller sample, the association between baseline risk and incident PD was overall weaker (HR 3.44; 95% CI 0.85‐13.99; P = .084; see Table 4), but the addition of GBA and LRRK2 variants in the algorithm improved the strength of association between baseline risk and incident PD (HR 4.22; 95% CI 1.21‐14.73; P = .024).
