Figure 4. Mean mobility improvement scores for real and sham prism glasses.

Figure 4

Participants who continued prism wear reported significantly more improvement with real than sham glasses. Mobility scores are in logit units: more positive values represent greater improvement. For real and sham prisms, error bars are 95% confidence intervals of the mean scores. For the difference between real and sham, errors bars are 95% confidence intervals of the mean paired differences.
