Overview

Top Research Topics at Trials?

Trials facilitates discussions on Randomized controlled trial, Clinical trial, Physical therapy, Internal medicine and Psychological intervention. The journal tackles topics on Randomized controlled trial, which can potentially contribute to the wider field of Surgery. It facilitates discussions on Clinical trial that incorporate concepts from other fields like Alternative medicine, Protocol (science), Adverse effect and Family medicine.

Trials explores topics in Physical therapy which can be helpful for research in disciplines like Acupuncture, Physical medicine and rehabilitation and Quality of life (healthcare). The work on Internal medicine tackled in the journal brings together disciplines like Oncology and Cardiology. The concepts on Psychological intervention presented in it can also apply to other research fields, including Mental health and Health care.

The majority of Psychiatry studies in the journal are focused on the subject of Anxiety. The Intervention (counseling) study featured falls within the wider field of Nursing. Research on Research design addressed in Trials frequently intersections with the field of MEDLINE.

Randomized controlled trial, Clinical trial, Internal medicine, Physical therapy and Protocol (science) are among the topics commonly tackled in Trials. The research on Randomized controlled trial tackled can also make contributions to studies in the areas of Psychological intervention, Placebo, Quality of life and Intervention (counseling). While work presented in it provided substantial information on Psychological intervention, it also covered topics in Mental health and Quality of life (healthcare).

Acupuncture, Traditional Chinese medicine, Adverse effect and Family medicine are some topics wherein Clinical trial research discussed in Trials have an impact. The journal focused on Physical therapy research but expanded to cover Anxiety. The studies on Rehabilitation discussed can also contribute to research in the domains of Stroke and Physical medicine and rehabilitation.

The most cited articles from the last journal are:

Publication chance based on affiliation

The publication chance index shows the ratio of articles published by the best research institutions in the journal edition to all articles published within that journal. The best research institutions were selected based on the largest number of articles published during all editions of the journal.

The chart below presents the percentage ratio of articles from top institutions (based on their ranking of total papers).Top affiliations were grouped by their rank into the following tiers: top 1-10, top 11-20, top 21-50, and top 51+. Only articles with a recognized affiliation are considered.

During the most recent 2021 edition, 3.80% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 14.62% were posted by at least one author from the top 10 institutions publishing in the journal. Another 10.23% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 16.52% of all publications and 58.63% were from other institutions.

Returning Authors Index

A very common phenomenon observed among researchers publishing scientific articles is the intentional selection of journals they have already attended in the past. In particular, it is worth analyzing the case when the authors participate in the same journal from year to year.

The Returning Authors Index presented below illustrates the ratio of authors who participated in both a given as well as the previous edition of the journal in relation to all participants in a given year.

Returning Institution Index

The graph below shows the Returning Institution Index, illustrating the ratio of institutions that participated in both a given and the previous edition of the conference in relation to all affiliations present in a given year.

The experience to innovation index

Our experience to innovation index was created to show a cross-section of the experience level of authors publishing in a journal. The index includes the authors publishing at the last edition of a journal, grouped by total number of publications throughout their academic career (P) and the total number of citations of these publications ever received (C).

The group intervals were selected empirically to best show the diversity of the authors' experiences, their labels were selected as a convenience, not as judgment. The authors were divided into the following groups:

  • Novice - P < 5 or C < 25 (the number of publications less than 5 or the number of citations less than 25),
  • Competent - P < 10 or C < 100 (the number of publications less than 10 or the number of citations less than 100),
  • Experienced - P < 25 or C < 625 (the number of publications less than 25 or the number of citations less than 625),
  • Master - P < 50 or C < 2500 (the number of publications less than 50 or the number of citations less than 2500),
  • Star - P ≥ 50 and C ≥ 2500 (both the number of publications greater than 50 and the number of citations greater than 2500).

The chart below illustrates experience levels of first authors in cases of publications with multiple authors.

Nursing Research Significance and Its Contribution to the Field

An integral and often overlooked field of study in the Trials journal is Nursing. The significance of nursing research lies in its commitment to advancing healthcare, influencing health policies, and improving patient outcomes. Various studies involving interventions, counseling, and mental health discussions are directly applicable to this field. In fact, many of these concepts and applications have also been observed in some of the accredited nursing schools in Mississippi. These institutions have been vital in incorporating research topics on anxiety, mental health, healthcare, and intervention counseling into their curricula in a bid to produce competent and up-to-date healthcare professionals. The said educational establishments' contribution to the medical field is not only through the academic preparation of future nurses but also by participating in various research studies similar to those featured in the Trials journal. Their shared focus on improving healthcare and patient outcomes is a testament to the importance of research inclusion in nursing studies. Just like the journal, these nursing schools look beyond the traditional roles and methodologies in care provision they strive to develop and apply evidence-based practices grounded on the latest research findings. The symbiosis between the two sectors is essential in advancing the nursing profession and, ultimately, the broader health care industry.
