For the present study, the PCA of residual test reporting 77.5% of variance was explained by Rasch measures.
The cohort study that was included could be strengthened by reporting estimates of variance and number of withdrawals, controlling for confounders in the analysis, and examining harms outcomes.
Only 40% reported effect sizes, 56% reported mean values, and 47% reported indices of variance (e.g., standard deviations/standard errors).
The expression data were reanalyzed using a previously reported analysis of variance (ANOVA) approach [7], here extended with a procedure to eliminate deviating probes.
For these compounds, additional high-quality studies (that report measures of variance) are required to increase the power of weighted meta-analyses.
Therefore, we used a more lenient P-value threshold for prioritization and annotation of a set of 'promising' SNPs, reported estimates of variance explained by all GWAS SNPs and made available the complete set of our GWAS results.
The intervention led to greater knowledge and more positive attitudes about therapy (reported analysis of variance: patient orientation, ethnicity, gender: F 1,149) = 9.44, P<0.01; n values not available for calculation of effect sizes).
To account for correlation among repeated measures, we assessed the intervention effects using generalized estimating equations in SAS PROC GENMOD (version 9.1; SAS Institute Inc., Cary, NC, USA), selecting autoregressive covariance within subjects and reporting sandwich estimators of variance.
One study did not report any estimates of variance and did not contribute data to the meta-analyses.
27 The final study (n = 65 671) reported the percentage of variance in similarity of recorded GP consultations among family members explained by family influence.
