Does source of funding and conflict of interest influence the outcome and quality of spinal research
TL;DR: A significant association between source of funding, study outcome, and LOE in spinal research was demonstrated and a large proportion of industry funded research was shown to provide level IV evidence and report favorable outcome.
Journal ArticleDOI
Comparison of Impact Factor, Eigenfactor Metrics, and SCImago Journal Rank Indicator and h-index for Neurosurgical and Spinal Surgical Journals.
TL;DR: Evidence is provided that the newer indices may be used interchangeably with the Impact Factor in this context, and they may, theoretically, mitigate some the shortcomings of the impact factor.

TL;DR: The data show that the majority of the recommended readings for the OITE stem from higher impact general orthopaedic and major subspecialty journals, and a preponderance of Levels IV and V research, which may suggest that test-takers may find benefit in the review of high-level general orthopedic journals and review articles in particular while preparing forThe OITE.

Strategies to improve the credibility of meta-analyses in spine surgery: A systematic survey
Nathan Evaniew,Leon van der Watt,Mohit Bhandari,Michelle Ghert,Ilyas S. Aleem,Brian Drew,Gordon H. Guyatt +6 more
TL;DR: The credibility of many current spine surgery meta-analyses is limited and researchers can improve future meta-Analyses by performing exhaustive literature searches, addressing possible explanations of heterogeneity, presenting results in a clinically useful manner, reproducibly selecting and assessing primary studies, addressing confidence in the pooled effect estimates, and adhering to guidelines for complete reporting.

The measurement of observer agreement for categorical data
J. R. Landis,Gary G. Koch +1 more
TL;DR: A general statistical methodology for the analysis of multivariate categorical data arising from observer reliability studies is presented and tests for interobserver bias are presented in terms of first-order marginal homogeneity and measures of interob server agreement are developed as generalized kappa-type statistics.
Journal ArticleDOI
Why the impact factor of journals should not be used for evaluating research
TL;DR: Alternative methods for evaluating research are being sought, such as citation rates and journal impact factors, which seem to be quantitative and objective indicators directly related to published science.

Introducing levels of evidence to the journal.
TL;DR: This section introduces orthopaedic surgeons to recent randomized trials relevant to the practice of orthopairedic surgery published in forty-two journals other than The Journal of Bone and Joint Surgery.

Journal impact factor: a brief review
TL;DR: The journal impact factor was created in the early 1960s to help select journals for the Science Citation Index (SCI), but it did not occur to me that it would one day become the subject of widespread controversy.
