Recent Bibliometrics of the Journal and Thank You to Our Reviewers

Abstract

Not available

Both Clarivate™ and Elsevier recently released their journal bibliometric measurements. We are incredibly pleased to report that the Impact Factor (IF) reported by Clarivate™ of the Neurologia i Neurochirurgia Polska (also known as Polish Journal of Neurology and Neurosurgery, PJNNS) remains stable at 2.9 (Fig. 1, bars). In post-COVID-19 times, many highly cited journals were not able to maintain their IF score. The IF score for 2023 was calculated by taking the number of citations in 2023 of all items published in PJNNS in 2021 and 2022, including editorial notes, invited editorials, invited review articles, review articles, research papers, short communications, and letters to the editors and dividing that number by the total number of research papers, short communications, invited reviews, and review articles published in 2021 and 2022 years. However, the PJNNS journal has moved from Q3 level in 2022 to Q2 level in 2023 (Fig. 1, line). This is an important achievement. Currently, PJNNS is ranked 99/277 in Web of Science™ category, “Clinical Neurology”.

Figure 1. PJNNS’s Impact Factor (IF) Trend. Despite the same value of IF for 2022 and 2023 (IF = 2.9, bars), PJNNS has achieved higher ranking in journal IF (JIF) assessment (line). PJNNS has moved from Q3 to Q2 (JIF percetile rose from 45.5 in 2022 to 64.4 in 2023). Source: JCR Edition 2024 by Clarivate Analytics

Elsevier’s Scopus CiteScore™ (CS) of PJNNS has risen from 3.4 in 2022 to 4.2 in 2023 (Fig. 2). Scopus CS measures the bibliometric status of the journal differently than Clarivate™ IF. Calculations of current CS include a period of 4 years, including citations of the calculation’s year and count all published items (ie, editorial notes, invited editorials, invited review articles, review articles, research papers, short communications, and letters to the editors). The steady increase of PJNNS’s Scopus CS is very encouraging.

Figure 2. PJNNS’s Elsevier Scopus CiteScore™ (CS) Trend. CS represents a key bibliometric parameter measuring the journal’s standing and is calculated from the Scopus database. CS has demonstrated a systematic growth for PJNNS. Current CS is based on the number of citations received by the journal in the last 4 years (including the calculation year) divided by the number of documents published (all items) in the journal in those 4 years. Based on this measure, PJNNS has been ranked 125/551 (77th percentile) in the Scopus category, “Medicine/Surgery”, and 187/400 (53rd percentile) in the category, “Medicine/Neurology (Clinical)”.

Moreover, the PJNNS Immediacy Index (ImI) calculated by Clarivate™ has also substantially improved (Fig. 3). ImI counts the citations to the journal’s published items in the current year. Thus, it represents the bibliometric measure of relevance of published articles in the same year. The ImI of PJNNS has systematically increased from 0.3 in 2019 to 1.4 in 2023.

Table 1 presents the 11 most cited articles in 2021 and 2022 that contributed to PJNNS’s 2023 IF (3 had an equal number of citations). Seven were research papers and 4 were review articles. They dealt with a wide-spectrum of neurologic conditions, including stroke, neurologic manifestations of COVID-19, and movement disorders.

The status of PJNNS would never be possible without the contribution of authors and tireless work of the Journal’s peer reviewers. The editors of PJNNS and the administrative staff of our Journal’s publisher, Via Medica, are incredibly grateful to our reviewers for their generous commitment to the Journal. The editors truly understand the effort and time required to review the submitted articles. Thus, as a small token of appreciation, we present here a list of our dedicated reviewers (Table 2). We highlighted in green those reviewers who provided 3 or more reviews in 2023.
