Erratum: A comparison of methods to estimate the survivor average causal effect in the presence of missing data: A simulation study (BMC Medical Research Methodology (2019) 19 (223) DOI: 10.1186/s12874-019-0874-x)

In the original publication of this article [1], the incorrect causal diagram was submitted as Fig. 1. The figure published in the original article depicts an exposure measured at two study waves. The correct causal diagram is presented in two panels and represents the relationship between an exposure measured at a single study wave and the outcome. This correction does not impact the original figure legend or manuscript. The corrected Fig. 1 is shown below.
