Frequency distributions of trunk inclination. Comparison of histograms of the fractions of time with trunk inclination in the sagittal (above) or lateral plane (below) for operations with direct and monitor endoscopy - mean and standard deviation (direct endoscopy: n = 10, monitor endoscopy: n = 9), * = significantly different (p < 0.05). Specifications of the trunk inclination angles are provided in the insets.
