Of the Wellcome Trust Case Control Consortium 2. Data were assessed by the following analyses: descriptive statistics; Pearson's linear correlation; and geostatistics. Association tests were performed at both loci using refractive error (spherical equivalent), axial length, corneal curvature, and anterior chamber depth as the phenotypes. A simple litmus test is that if more than 15% of the enrolled cases did not have complete data for analysis or dropped out of the study for other reasons, the study becomes suspect for a selection bias. Imputation was performed using MACH version 1.1.16, and statistical analysis was conducted using PLINK. Results were considered statistically significant at P < 0.05. A full list of contributing investigators to the generation of these data is available online in Appendix 1 (http://aaojournal.org). Two independent parameters were measured: the sample's .. Data were analyzed by one-way analysis of variance (ANOVA), followed by assessment of differences by Tukey's post-hoc test. Measurements were performed on IOLs with increasingly complex surface geometries: spherical surfaces, surfaces modelled by higher-order Zernike terms, and freeform surfaces from biometrical patient data. All statistical calculations were performed using SPSS version 16.0 [25]. Arrows show numerous spherical vacuoles of fat droplets. On georeferenced points, both soil and seeds were sampled for analysis of soil fertility and seed physiological potential. The small standard deviation in the ROC acquisition demonstrates the minor amount of statistical errors in the acquisition of the CE and MP positions. Oral administration of whey proteins products showed a positive effect on the . Data are expressed as the mean ± standard deviation (SD).
