Fig 5

Box-and-whisker plots of the maximum absolute amplitude of inter-CBCT session marker displacement using breath-hold. The amplitudes in the SI direction in all sites were significantly larger than all other directions, except the AP direction in Lt. Ut: upper thoracic esophagus; Mt: middle thoracic esophagus; Lt: lower thoracic esophagus /esophagogastric junction; RL: right–left; AP: anterior–posterior; SI: superior-inferior.
