HBPP: Home-based pencil push-up therapy

HBCVAT+: Home-based computer vergence/accommodative therapy and pencil push-ups

OBVAT: Office-based vergence/accommodative therapy with home reinforcement

OBPT: Office-based placebo therapy with home reinforcement

CI: Confidence Interval

Total Change: Week 12 minus baseline

a

Adjusted for measurement obtained at the baseline examination

b

The blur finding was used, but if the patient did not report a blur, the break finding was used
