Dotplot for July 2011 through December 2011 for the pulse oximetry measured oxygen saturation (Spo2) metric. The blue hexagons represent the anesthesiologists with a significantly greater incidence of Spo2 first checked ≥5 min after induction than the other anesthesiologists based on the criteria of Ehrenfeld et al.,3 without covariate and multiple comparison adjustment. The green triangle shows the single anesthesiologist who was an outlier when the Bayesian method was applied without covariate adjustment. This anesthesiologist is also a frequentist outlier, which is why the symbol also includes some blue. None of the anesthesiologists was detected as having a significantly greater incidence of Spo2 first checked ≥5 min after induction than the other anesthesiologists when the Bayesian method was applied with covariate adjustment. Unadj = unadjusted.
