Distribution of α angle in the AT and PT groups

AT (n=24)PT (n=19†)
α*<5511 (46%)7 (36%)
55 < α*<699 (37%)6 (32%)
α*>694 (17%)6 (32%)
Mean α angle**58.0° (SD 10.6)62.0° (SD 13.0)
  • *p=0.54 (Fisher's exact test).

  • **p=0.26 (two-sample t test).

  • †In two patients, the α angle could not be measured.

  • AT, active treatment; PT, passive treatment.
