A histogram showing the frequency of coil shifts observed in our cohort. The bin size used was 0.5 mm, centered about the value shown on the x‐axis. These data show that large coil shifts tend to be less frequent than the small shifts, with a median coil shift value of 0.7 mm. The most frequently occurring coil shift is at 0.5 mm (i.e., between 0.25 and 0.75 mm).
