2. Materials and Methods
2.3. Identifying Full-Text Publications
2.4. Impact Factor Analysis
The ISI Web of Knowledge citation database (Philadelphia, USA) was used to determine the 2010 impact factor for each journal. Publications in journals not indexed or in journals that did not have an impact factor listed were excluded from the analysis.
2.5. Statistical Analysis
Categorical variables were compared using chi-square test. Continuous variables were reported as means with standard deviations or in the case of outliers as medians. Continuous variables were compared using the t test. To determine predictors of full-text publication, odds ratios and their corresponding 95% confidence intervals were calculated using univariate and multivariate logistic regression analysis. All statistical analyses were performed by using SPSS (version 18.0 for Windows).
3.2. Publication Rate and Time to Publication
3.3. Journal of Publication and Impact Factor
Articles were published in 121 different journals with 236 (61.4%) of publications in dedicated neurosurgery journals and one-third of publication occurring in either Neurosurgery or the Journal of Neurosurgery. The top 8 journals in which publications occurred and their 2010 impact factors are listed in Table 2. The overall mean impact factor for all publications was 3.319 (0.309 - 53.484). The mean impact factor for publication in dedicated neurosurgery journals was 2.75 compared to a mean impact factor of 3.80 for publications in all other journals.
