Fig. 7From: The treatment zone decentration and corneal refractive profile changes in children undergoing orthokeratology treatmentThe association between TZ decentration and summed RCRP at different chord radii. A Correlation between TZ decentration and summed RCRP at radius 1.5 mm. B Simple linear regression showed that the percentage of the variance of Summed RCRP could be explained by TZ decentration at different chord radii.
