Figure 5.
Cumulative frequency distribution plots indicating the percentage of M (panel A) and J0 (panel B) power vector values within a given dioptric difference from gold-standard retinoscopy. Panel C provides data of repeatability of the M power vector for all three techniques in the same format as panels A and B. The dioptric difference shown along the abscissa of all three panels is unsigned absolute values, unlike the Bland-Altman plots in Figures 1 to 3. The abscissa range in the three panels is different to demonstrate the data trends.
