Fig. 1From: Addressing misclassification bias in vaccine effectiveness studies with an application to Covid-19Results of simulations for non-differential (A) and differential (B) misclassification scenarios. Bias is defined as the ratio between the estimated and the true OR. Dashed horizontal indicates no bias.
