While AUC values were only slightly above 0.5, their p -values remained highly significant, even under a strict threshold ( p < 5e -8 ), except for the irritability item ( p = 7e -5 ).

Each predictive model included a PRS, along with age and sex, and was poorly predictive of BCC risk in the Hispanic/Latino sample from the GERA cohort with an area under the curve (AUC) value of 0.545 and 0.573, depending on the threshold of significance for the SNPs ( P -value < 5.0 × 10 -8 and P < 1.0 × 10 -6 , respectively) (Supplementary Fig. 8 ).

Three SNPs were highly significant ( p < 5 × 10 −8 ): rs651821 , rs6494835 and rs8035009 ( Fig 2 ).

Pairwise Comparisons between Composites All the 3 Tukey's pairwise comparisons between the Δb parameters of 3 composites became highly significant (all P values <0.00000005, Figures 3 and 4 , Table 1 ). 3.2.2.

41 A follow-up GWAS of copper, selenium, and zinc identified eight highly significant ( p < 5 × 10 − 8 ) common genetic variants that mapped to loci containing genes with roles in trace element metabolism. 42 These genetic variants accounted for 4%–8% of phenotypic variance in copper, selenium, and zinc.

S1 ) and revealed 76 SNPs with highly significant ( P < 5e−8) associated with the striped phenotype ( Fig.

We first identified all SNPs within 10 000 kb of a nominally significant ( P -value < 5 × 10 −8 ) GWAS locus with r 2 > 0.6 in the 1000G EUR population to the index SNP, using PLINK 1.9.

Potential causal effects between CKD and RCC With a highly significant threshold of P<5×10 −8 , we selected 22 SNVs associated with CKD as instrumental variables.

We considered SNPs with a one-tailed p < 0.05 in our primary sample to be nominally significant; in the overall meta-analysis, SNPs with a two-tailed p < 5.00 × 10 −8 was considered genome-wide statistically significant.

The observed associations suggest that quasi-significant SNPs (10 − 5 < p < 5 × 10 − 8 ) and SNPs at the genome wide level of statistical significance ( p < 5 × 10 − 8 ) may have a similar proportions of risk associated SNPs.

We also noted that NAALAD2 , a member of the N -acetylated alpha-linked acidic dipeptidase (NAALADase) gene family whose inhibition results in a reduction in aggressive behavior ( 45 ), showed significant signatures of selection (XP-EHH, ∆ π , ∆ r 2 ) in the terrier breeds tested, despite lacking a highly significant SNV ( P < 5 × 10 −8 ).

Only a borderline significant association was found between PGS p < 5 × 10 −8 for diabetes and sural SNAP amplitude (β = −0.25, 95% CI = −0.52 to 0.02; Table S1 ).

By utilizing the indicative significance level ( P < 5 × 10 −8 ), LD clumping, harmonization, and F-statistics > 10, a total of 13 and 103 SNPs were identified for FBI and TBI, respectively.

Including rs74653330 (p.Ala481Thr), a missense lead variant in OCA2 , a total of 12 independent nonsynonymous variants associated with skin color traits were identified in the GWAS (Supplementary Data 5 ): 1 in a previously unreported locus, 9 in previously reported loci, and 2 in nominally significant loci (top variants of 2 loci did not pass the genome-wide significance level, P < 5.0 × 10 −8 ).

A p value < 1 × 10 −5 was considered as suggestive of significance and a p value < 5 × 10 −8 was regarded as having genome-wide significance. 3.

Results for GWAS were separately described in Table 8 and Table 9 depending on whether p -value was adequately significant ( p < 5 × 10 −8 ) or was situated on the boundary of statistical significance (0.05 < p < 5 × 10 −8 ). 3.

At 105 of 152 evaluated regions the main signal demonstrated genome-wide significance, while 44 were marginally significant (9.89×10 -5 ≥ p-value > 5×10 -8 ).

It was immediately clear from the sample size that even for minor allele frequencies (MAF) above 20% we would find at best nominally significant evidence for associations from this study alone (0.05 > p ≥ 5 × 10 −8 ; [ 33 ]).

In complex diseases such as SLE, where many different genes make a modest contribution to disease susceptibility, it is necessary to perform large-scale association studies to combine results from several datasets, to have sufficient power to identify highly significant novel loci ( P <5×10 −8 ).

For schizophrenia, enrichment in brain is much stronger than in any other tissue type ( p = 3.26×10 −19 ), while highly significant enrichment could be observed in heart ( p = 5.02×10 −8 ) and blood ( p = 1.23×10 −6 ) as well.

We initially observed that when cases with relatively short telomeres (ie, in the first and/or second quartiles) were studied, the effect of the rs10936599 genotype was not significant, whereas a significant effect was seen in the third quartile and a highly significant effect (ln(OR) −0.43, p=5.04×10 −8 ) was seen in the fourth quartile.

This decline was highly significant (p=5.06e−08, N = 18) but the p-value calculation did not account for non-independence across years (the same prevalent cases may be included in multiple years).

LDHC showed a highly significant reduction in TIF after DTX treatment ( P = 5.06 × 10 −8 ), confirming that it is contributed to TIF by the seminiferous tubules in mice. 23 Thus, mouse TIF contains hundreds of germ cell proteins, many of which are predominantly or only expressed in developing sperm that reside “inside” the blood‐testis barrier.

Whilst both models indicated a highly significant relation between heritability and hierarchical level ( F -tests; linear: R 2 = 0.49, F 1,44 = 43, p = 5.1 × 10 −8 ; quadratic: R 2 = 0.67, F 2,43 = 44.1, p = 3.8 × 10 −11 ), the quadratic model fitted the data better than the linear model ( F -test, F 1,43 = 23.3, p = 1.8 × 10 −5 ) because heritability increased significantly from V1 to V3 ( t -test, t 8 = 2.38, p = 0.04).

Furthermore, only highly significant variants ( P ≤ 5·10 −8 ) will be selected in order to avoid false positives, but also potentially reducing the number of selected variants.
