Figure 2: Bland–Altman plots of the comparative analyses performed in the current study. (a) Comparison between the PIOLobtained using the classical keratometric approach (PIOL1.3375k) and that obtained using the Gaussian equation (PIOLGaussian). (b) Comparison between the PIOLobtained using the adjusted keratometric approach (PIOLadjk) and that obtained using the Gaussian equation (PIOLGaussian). (c) Comparison between the PIOLobtained using the adjusted keratometric approach (PIOLadjk) and that obtained using the True Net estimation (PIOLTrue Net). (d) Comparison between the PIOLobtained using the True Net approach (PIOLadjTrue Net) and that obtained using the Gaussian equation (PIOLGaussian). Upper and lower lines represent the limits of agreement calculated as mean of differences ± 1.96 standard deviation |
