Comparison of the numerical differences in prediction accuracy across feature sets revealed a similar pattern to the ML classification results: prediction accuracy was clearly non-significant for the “sMRI subcortex” model, marginally non-significant for the “sMRI only” model and clearly significant for the “restFC only” model 5 .

Results After seven days of intervention, the mean increase from baseline in the Glasgow coma scale (GCS) score was significantly higher in the curcumin compared with the placebo group ( P -value: 0.028), while the reduction in the APACHE-II score in the curcumin group was greater than that the placebo group in a marginally non-significant fashion ( P -value: 0.055).
With regard to diagnostic sensitivity, we demonstrated that HyFoSy was equivalent (higher sensitivity but marginally non-significant difference) to HyCoSy, the ultrasonographic alternative.
There was a significant interaction between female selection history and food quality and a marginally non-significant main effect of female selection history (Table 1 ).
Although this result was marginally non-significant, the magnitude and direction of the pooled estimate remained broadly consistent with the main analysis.
Considering the host origin, a weak and marginally non-significant differentiation is found between human and dog strains for L. archibaldi , while a strong differentiation seems to affect L. infantum strains between the two host species ( Table 2 ).
To test the presence of this strategic rounding-off, the proportion of marginally significant p -values ( p -values between 0.045 and 0.049) are compared with the marginally non-significant p -values ( p -values between 0.051 and 0.054).
Subgroup analysis by dialysis or non-dialysis status indicated that the risk of SAEs was statistically significant in the anemic CKD patient group not receiving dialysis (pooled OR = 1.15; 95% CI: 1.01–1.30; I 2 = 0.0%) ( Figure 4 a), while it was marginally non-significant in the dialysis patient group (pooled OR = 1.12; 95% CI: 0.99–1.26; I 2 = 0.0%) ( Figure 4 a).
In a binomial GLMM across n = 182 males from 10 isolines, the four-way interaction was not statistically significant ( β = 1.937 ± 1.659, Z = 1.168, p = 0.243), but day again contributed to several interactions (though some marginally non-significant; electronic supplementary material, table S19).
Among intervention types, Taichi (Estimate = 0.35, p = 0.02) showed a significant positive effect compared to Meditation, while Yoga (Estimate = 0.07, p = 0.43) and Qigong (Estimate = 0.19, p = 0.07) had a marginally non-significant positive effect.
The effect of home range size on tick abundance was negative, but marginally non-significant.
As the effect of treatment was only marginally non-significant, we performed post-hoc tests to look at differences between fresh and longer-lived sperm, and fresh and diluted sperm independently.
Considering our small sample size, it is certainly possible that despite the marginally non-significant p-value, helmeted birds do show an even stronger Lombard effect than unhelmeted birds.
This marginally non-significant result may be caused by Type II error, and may have been different in a larger scale study.
Notably, this association remained significant in the male-specific model but became marginally non-significant among female adolescents after adjusting for other covariates in the final model.
The UCB group showed a marginally non-significant improvement over the control group, without statistical differences in most outcome measures.
There was a marginally non-significant tendency for first litters of iteroparous females to develop more slowly than litters of semelparous females (age at eye opening 66±0.8 days in first litters, 64±0.8 days in both second litters and offspring of semelparous mothers; overall model: F 2,29 = 1.7, P = 0.19, difference in age at eye opening between litters with semelparous mothers and first litters of iteroparous mothers: t = −1.9, df = 29, P = 0.07; difference between first and second litters of iteroparous mothers t = −1.2, df = 29, P = 0.24).
The main effect of treatment was not significant, but there was a marginally non-significant interaction between valence and treatment on latency to probe, that occurred because birds from low-competition nests were faster to probe Near POS cues than birds from high-competition nests (GLMM: B = 0.20 ± 0.10, X 2 (1) = 3.79, p = 0.052; Fig 1B ).Thus, when overall speed is controlled for, as predicted, there is some evidence, albeit marginally non-significant, that birds from small broods had a higher expectation of reward in the face of ambiguous information.
The results of the PERMANOVA showed that the association of alkalinity with microbiota composition was marginally non-significant ( Table 1 b); however, the Mycobacterium genus was found to be significantly more abundant in the high alkalinity group ( Figure 3 ).
However, these differences were marginally non-significant when the block was instead modelled as a fixed effect.
Therefore, wherever, in the present study, a marginally non-significant p -value was found within the clinical group, it should be interpreted with caution, as it might have been statistically significant had the sample been as large as the control group.
This analysis gave a marginally non-significant effect of the interaction between Type and Neighbor but significant additive effects of these ( Table 3 ).
Sandvig, Coulson & Clegg (2019) showed that among altricial birds, island birds tend to grow slower than continental birds, though the relationship is marginally non-significant.
Although the same trend was evident for females as well, the statistical analysis did not detect it (marginally non-significant).
If we conduct a Bonferroni correction, the brain size effect becomes marginally non-significant.
