The method error (reproducibility) after 2 years was 1.1degrees for sagittal and transversal measurements. The mean change in NHP measurement was -0.3degrees for both measurements, and the variance was 1.21degrees (= 1.1(2)).en10.1067/mod.2003.71info:eu-repo/semantics/openAccessArticle123445145412695773Q1WOS:000182330400013Q3
