Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Abstract Objective: The goal of this study was to compare the reporting rigour of the literature searching component of systematic reviews with, and without, the help of a librarian.Methods: Systematic reviews published from 2002 to 2011 in the 20 highest Impact Factor paediatrics journals were collected from MEDLINE. Corresponding authors were contacted via an email survey to determine if a librarian was involved, the role played, and functions performed. The reviews were scored using a 15 item checklist by two reviewers independently. The overall reporting for each role category was expressed as the mean value of the total score. Analysis of variance (ANOVA) and Pairwise comparisons were used for multiple comparisons. The comparison of frequency of reported methodological elements between different role categories was accomplished using Pearson Chi-square analysis, and expressed as the risk ratio (RR) with 95% confidential interval (CI).Results: 186 reviews met the inclusion criteria. 44% of the authors indicated the involvement of a librarian in conducting the systematic review. In the presence of a librarian as the co-author/team member, the mean score was 8.40, (95% CI 7.69-9.11) compared to 6.61, (95% CI 6.26-6.95, p <0.001) for reviews without a librarian. The presence of the librarian as a co-author/team member was correlated with higher scores for reporting in various components of the methodology, in comparison to studies without a librarian, particularly the flow diagram of study inclusion process (RR=1.76, 95% CI 1.36-2.30), the date search was updated (RR= 2.29, 95% CI 1.32-3.98), the full search strategy (RR=3.55, 95% CI 1.81-6.97), the use of subject-specific and regional bibliographic databases (RR=1.94, 95% CI 1.57-2.40), and searching grey literature (RR=1.72, 95% CI 1.17-2.53).Conclusions: Our results show that having a librarian or information professional as a team member or co-author contributes to more rigorous reporting of the literature searching component of systematic reviews.
