Although PCA resulted in a marginal nonsignificant improvement, it performed less well than the group-specific metrics (figs. 1 3; supplementary figs. S2 S6, Supplementary Material online).
As these negative test-retest results for the slopes are in essence nonsignificant correlations, it is important to consider the power of our analysis.
For HFE genotype, results were nonsignificant, but it may be noted that in both men and women the minor allele homozygotes (YY or DD) had the lowest mean lead levels.
Performance was best with the revolving stage menu, and there was a nonsignificant tendency for it to be rated as preferred by the participants.
However, for prenatal p,p´-DDE, removing Michalovce doubled the estimate (from 0.12; 95% CI: 0.03, 0.22 to 0.23; 95% CI: –0.09, 0.54) and made it nonsignificant (see Supplemental Material, Table S8).
Additional adjustment for BMI to explore residual confounding showed weaker nonsignificant associations, but it is questionable whether inclusion of BMI represents overadjustment because BMI and sex hormone levels are on the same pathway.
Moreover, for the number of empty grain per panicle, we observed a slight and nonsignificant reduction of it for the irrigated accessions in the upland condition (Student's t-test, P = 0.29, Additional file 7) but a dramatic decrease of it for the upland accessions (Student's t-test, P = 5.9e-07, Additional file 7), suggesting another adaptive trait of upland rice.
If there were means outside this range the procedure is repeated with comparisons with the second highest and so on until the lowest (highest) value is included in a nonsignificant range or it is declared significantly different from the nearest mean.
However, it is nonsignificant after Bonferroni's correction (Table 2).
Heterogeneity was present in efficacy outcomes, although it was nonsignificant in safety outcomes.
