APE = arithmetic prediction error; AL = axial length; WTW = white to white; Kmean = mean keratometry; ELP = effective lens position
Table shows the correlation between the APE of the investigated formulae and AL, WTW, tKmean values, ELP, decentration and tilt calculated by univariable regression models
For multiple testing, adjusted P value (using Bonferroni correction) below 0.0083 indicates that the slope deviates significantly from zero
Values in bold letters represent statistical significance
