Robust ivw
WebThe leave-one-out analysis showed that each single nucleotide polymorphism (SNP) of AS was robust to each outcome. No significant causal effects were found between AS, RA and LTL in the reverse MR analysis. ... The IVW results showed a significant association between LTL and ankylosing spondylitis (OR = 1.55, 95% CI: 1.14-2.11). WebDec 20, 2024 · These data were then analyzed using the penalized robust IVW method (Burgess et al., 2016). The IVW estimate is the same as the two-stage least squares estimate using individual-level data. The penalization of weights from candidate instruments produces heterogeneity in causal estimates, which generates the penalized IVW method, …
