Null models in network neuroscience.
Váša F, Mišić B. Váša F, et al. Nat Rev Neurosci. 2022 Aug;23(8):493-504. doi: 10.1038/s41583-022-00601-9. Epub 2022 May 31. Nat Rev Neurosci. 2022. PMID: 35641793 Review.
Here we describe the logic, implementation and interpretation of null models of connectomes. We introduce randomization and generative approaches to constructing null networks, and outline a taxonomy of network methods for statistical inference. ...Finally, we consi …

CD28 (null) CD4 T-cell expansions in autoimmune disease suggest a link with cytomegalovirus infection.
Bano A, Pera A, Almoukayed A, Clarke THS, Kirmani S, Davies KA, Kern F. Bano A, et al. F1000Res. 2019 Mar 25;8:F1000 Faculty Rev-327. doi: 10.12688/f1000research.17119.1. eCollection 2019. F1000Res. 2019. PMID: 30984377 Free PMC article. Review.
Immunosenescence is often associated with the presence of an expanded population of CD4 T cells lacking expression of CD28 (CD28 (null)). These highly cytotoxic CD4 T cells were isolated from disease-affected tissues in patients with rheumatoid arthritis, systemic lupus er …

Causal null hypotheses of sustained treatment strategies: What can be tested with an instrumental variable?
Swanson SA, Labrecque J, Hernán MA. Swanson SA, et al. Eur J Epidemiol. 2018 Aug;33(8):723-728. doi: 10.1007/s10654-018-0396-6. Epub 2018 May 2. Eur J Epidemiol. 2018. PMID: 29721747 Free PMC article. Review.
Sometimes instrumental variable methods are used to test whether a causal effect is null rather than to estimate the magnitude of a causal effect. However, when instrumental variable methods are applied to time-varying exposures, as in many Mendelian randomization studies, …

Hyper-Null Models and Their Applications.
Zeng Y, Liu B, Zhou F, Lü L. Zeng Y, et al. Entropy (Basel). 2023 Sep 28;25(10):1390. doi: 10.3390/e25101390. Entropy (Basel). 2023. PMID: 37895511 Free PMC article.
Null models are crucial tools for investigating network topological structures. However, research on null models for higher-order networks is still relatively scarce. ...Lastly, we investigate the impact of hypergraph randomness on network dynamics using the propose

Null results in TMS: from absence of evidence to evidence of absence.
de Graaf TA, Sack AT. de Graaf TA, et al. Neurosci Biobehav Rev. 2011 Jan;35(3):871-7. doi: 10.1016/j.neubiorev.2010.10.006. Epub 2010 Oct 16. Neurosci Biobehav Rev. 2011. PMID: 20955732 Review.
It is always difficult to interpret null results. But as a research method, transcranial magnetic stimulation (TMS) has so many degrees of freedom that null results are often dismissed as meaningless. We feel that this may be unnecessary, if not counterproductive. …

Microsatellite null alleles in parentage analysis.
Dakin EE, Avise JC. Dakin EE, et al. Heredity (Edinb). 2004 Nov;93(5):504-9. doi: 10.1038/sj.hdy.6800545. Heredity (Edinb). 2004. PMID: 15292911 Free article. Review.
Highly polymorphic microsatellite markers are widely employed in population genetic analyses (eg, of biological parentage and mating systems), but one potential drawback is the presence of null alleles that fail to amplify to detected levels in the PCR assays. Here we exam …

Proportion of Infant Neurodevelopment Trials Reporting a Null Finding: A Systematic Review.
Finch-Edmondson M, Paton MCB, Honan I, Galea C, Webb A, Novak I, Badawi N, Trivedi A. Finch-Edmondson M, et al. Pediatrics. 2023 Feb 1;151(2):e2022057860. doi: 10.1542/peds.2022-057860. Pediatrics. 2023. PMID: 36695068
OBJECTIVES: Characterize the proportion of infant neurodevelopment trials reporting a null finding and identify features that may contribute to a null result. DATA SOURCES: The Cochrane library, Medline, Embase, and CINAHL databases. ...LIMITATIONS: Publication bias …

Near-Null Magnetic Field Suppresses Fruit Growth in Arabidopsis.
Xu C, Feng S, Yu Y, Zhang Y, Wei S. Xu C, et al. Bioelectromagnetics. 2021 Oct;42(7):593-602. doi: 10.1002/bem.22363. Epub 2021 Jul 21. Bioelectromagnetics. 2021. PMID: 34289513
We previously found that a near-null magnetic field affected reproductive growth in Arabidopsis under white light. To test whether the effect of a near-null magnetic field on fruit growth of Arabidopsis is related to cryptochrome, we grew wild-type Arabidopsis and c …

Lack of acute xenogeneic graft- versus-host disease, but retention of T-cell function following engraftment of human peripheral blood mononuclear cells in NSG mice deficient in MHC class I and II expression.
Brehm MA, Kenney LL, Wiles MV, Low BE, Tisch RM, Burzenski L, Mueller C, Greiner DL, Shultz LD. Brehm MA, et al. FASEB J. 2019 Mar;33(3):3137-3151. doi: 10.1096/fj.201800636R. Epub 2018 Nov 1. FASEB J. 2019. PMID: 30383447 Free PMC article.
To address this, we created 2 NOD- scid IL-2 receptor subunit gamma ( IL2rg) (null) (NSG) strains that lack murine MHC class I and II [NSG-beta-2-microglobulin ( B2M) (null) ( IA IE)(null) and NSG -( K(b) D(b)) (null) ( IA(null))]. We observed r …

Null-free False Discovery Rate Control Using Decoy Permutations.
He K, Li MJ, Fu Y, Gong FZ, Sun XM. He K, et al. Acta Math Appl Sin. 2022;38(2):235-253. doi: 10.1007/s10255-022-1077-5. Epub 2022 Apr 9. Acta Math Appl Sin. 2022. PMID: 35431377 Free PMC article.
The traditional approaches to false discovery rate (FDR) control in multiple hypothesis testing are usually based on the null distribution of a test statistic. However, all types of null distributions, including the theoretical, permutation-based and empirical ones, …
