The observed discordance in IgG leads to 4 sufferers suggests individual outcomes may be unreliable. Inappropriate affected individual selection through diagnostic error, anchoring bias, or selection bias could have occurred, although we attemptedto minimize this with multiple board-certified dermatologists review every patient’s photographs.
