Fig. 4From: External control arm analysis: an evaluation of propensity score approaches, G-computation, and doubly debiased machine learningLog width of the \(95\%\) Confidence Intervals (C.I) for the different methods. To measure the log width, we compute the logarithm of the variance of a Gaussian distribution which \(95\%\) C.I. would match the observed C.I. Each dot corresponds to a simulation study that includes 300 replicatesBack to article page
