“Academic genealogy” refers to the linking of scientists and scholars based on their dissertation supervisors. We propose that this concept can be applied to medical training and that this “medical academic genealogy” may influence the landscape of the peer‐reviewed literature. We performed a comprehensive PubMed search to identify US authors who have contributed peer‐reviewed articles on a neurosurgery topic that remains controversial: the value of maximal resection for high‐grade gliomas… Expand
Are other scientific genealogies reporting alternative facts?
The conclusion is (still) that the academic genealogy of scientific authors is predictive of their findings and this contributes to systematic bias in the published literature. Expand
Association between medical academic genealogy and publication outcome: impact of unconscious bias on scientific objectivity
Meta-analysis of articles contributed by authors belonging to the different medical academic genealogies yielded distinct and contradictory pooled point-estimates, suggesting that genealogy contributes to systematic bias in the published literature. Expand
‘Journal Bias’ in peer-reviewed literature: an analysis of the surgical high-grade glioma literature
An exhaustive search that identified articles exploring the question of whether survival benefit was associated with maximal high-grade glioma (HGG) resection found the distribution of these 108 articles among the 26 journals to be non-random (p<0.01). Expand
Academic Genealogy of Neurosurgery via Department Chair.
The academic genealogy in this study allows for any neurosurgeon trained in the United States to put his or her training into historical context and provides a reference for bibliographic research to quantitatively describe the influence of individuals and institutions on the field. Expand
Coevolution of Peer-Reviewed Literature and Clinical Practice in High-Grade Glioma Resection.
Clinical practice patterns mirror publication patterns for HGG resection, suggesting that neurosurgical oncology is a field in which clinical practice is informed by the peer-reviewed literature. Expand
The impact of authors’ medical specialty on publication patterns and published results of adjuvant radiotherapy for WHO grade 2 meningiomas—a systematic review
If a radiation-oncologist was the last author of the study, the study was more likely to favor adjuvant radiotherapy after gross total resection of WHO grade 2 meningioma, and Clinicians and researchers should be aware of a possible genealogy bias in the neuro- oncological literature. Expand

Advances in biomedicine and other fields of science and technology depend on research teams and their peer-reviewed publications. The scientific literature represents an invaluable socio-economicExpand
An Academic Genealogy of Psychometric Society Presidents
The genealogy of presidents of the Psychometric Society is presented by constructing a genealogical tree, in which Ph.D. students are encoded as descendants of their advisors, and shows that most of the presidents belong to five distinct lineages. Expand


Publication bias in neurosurgery: lessons from series of unruptured aneurysms
The solution to the problem of publication bias in the field of neurosurgery would be community-based prospective registration of all patients who underwent surgery, providing a sampling frame free from publication bias. Expand
A multivariate analysis of 416 patients with glioblastoma multiforme: prognosis, extent of resection, and survival.
Gross-total tumor resection is associated with longer survival in patients with GBM, especially when other predictive variables are favorable. Expand
The Value of Glioma Extent of Resection in the Modern Neurosurgical Era
Despite limitations in the quality of data, mounting evidence suggests that more extensive surgical resection is associated with longer life expectancy for both low- and high-grade newly diagnosed gliomas. Expand
The relationship between survival and the extent of the resection in patients with supratentorial malignant gliomas.
Future reporting of surgical results of patients with gliomas will require stratification by the known prognostic variables of age, histological findings, and performance status to characterize better this subgroup of young patients with favorable histology findings and good performance status for whom surgery is beneficial. Expand
IDH1 mutant malignant astrocytomas are more amenable to surgical resection and have a survival benefit associated with maximal surgical resection.
Therapeutic benefit from maximal surgical resection, including both enhancing and nonenhancing tumor, may contribute to the better prognosis observed in the IDH1 mutant subgroup. Expand

Little scientifically credible evidence is available to support the assertion that aggressive surgical resection prolongs survival, and well-planned and carefully executed prospective observational studies are needed. Expand

Practical recommendations on mentoring in medicine that are evidence-based will require studies using more rigorous methods, addressing contextual issues, and using cross-disciplinary approaches. Expand
Despite persistent limitations in the quality of data, mounting evidence suggests that more extensive surgical resection is associated with longer life expectancy for both low- and high-grade gliomas. Expand

It is argued that there is no entirely satisfactory way of dealing with COIs, but that all researchers should be aware of the issues discussed here to minimize the extent to which COIs can distort the scientific literature. Expand
Publication bias in clinical research
The presence of publication bias in a cohort of clinical research studies is confirmed and it is suggested that conclusions based only on a review of published data should be interpreted cautiously, especially for observational studies. Expand
