Figure 1
Box plots for vertical deviations (left) and cyclotorsional deviations (right) in patients with idiopathic or acquired superior oblique muscle palsy who had a single surgery or repetitive (two or more) surgeries. A box with a bar indicates the upper 75 percentile and lower 25 percentile, with a median, maximum, and minimum. Double-arrowhead bars indicate the 95% confidence interval. Note that the 95% confidence interval of vertical deviations is not overlapped with each other between the single-surgery group and repetitive-surgery group of idiopathic or acquired palsy. Minus degrees in cyclotorsional deviations indicate excyclotorsion.
