From: Comprehensive comparisons of ocular biometry: A network-based big data analysis
Meta-analysis results comparing all instruments with respect to astigmatism and astigmatism vectors. The upper right shows the direct comparisons meta-analysis between each pair of formulas and the bottom left shows the network meta-analysis between each pair of formulas. Weighted mean differences (95% confidence intervals) are calculated by column. J0, anterior corneal power vectors for the cardinal (axes at 90° and 180°) meridians; J45, anterior corneal power vectors for the oblique (axes at 45° and 135°) meridians; AST, astigmatism; NA, not available. The underline data indicate the statistical significant effect
