[The Conundrum of Relationships in the Multivariate Dataset of nvAMD Treatment].

Conclusion A switch in anti-VEGF therapy is not causally related to better VA outcome. In the statistical evaluation of non-randomised, retrospective case series, special attention must be given to potential confounding variables. When subgroups under investigation are not well balanced for confounding factors, misleading spurious correlations can result, leading to incorrect inferences. PMID: 29232756 [PubMed - in process]
