Fig. 2. Proportional bias of parent/carer-measured and orthoptist-measured iSight Test Pro visual acuity.

Fig. 2

Linear regression of (A) parent/carer iSight Test Pro and (B) orthoptist iSight Test Pro against standard of care visual acuity. Description: The 95% confidence intervals (CI) of the slope gradient span 0; the null hypothesis that level of standard of care visual acuity does not affect iSight Test Pro measure is accepted.
