Objective:

The objective of this investigation was to evaluate the agreement rate on judgments made using the Murad tool by different systematic review teams.

Introduction:

Evaluating the methodological quality of case reports and case series is challenging but some tools do exist for this purpose. We leveraged the presence of studies that have been evaluated by different systematic review teams to assess the inter-consensus agreement among different teams on Murad tool domains.

Methods:

Using a back-citation method, we identified systematic reviews that used the Murad tool and retrieved all the included primary studies. We selected studies that were assessed by more than 1 systematic review team. We calculated observed agreement and Gwet's agreement coefficient on judgments made about each signaling question.

Results:

We identified 982 systematic reviews that cited the Murad tool and collectively cited 59,080 references. The final data comprised of 81 duplicated case reports and series assessed by more than 1 systematic review team. Overall, the signaling questions had very high observed agreement with 5 of the 8 questions having agreement over 75%. The signaling questions with the highest agreement addressed the adequacy of the ascertainment of the exposure (coefficient 0.959), ascertainment of the outcome (coefficient 0.829), presence of a dose-response gradient (perfect agreement) and clarity of reporting (coefficient 0.755).

Conclusion:

The current study demonstrates overall high agreement among different systematic review teams that used the Murad tool for appraisal of the same case series and case reports. Leveraging duplicated studies across systematic reviews is a feasible way to retrospectively assess the reliability of tool.

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Methods of Documentation VI: Case Management Model

The case management model is a multidisciplinary approach that involves healthcare professionals from diverse disciplines, such as physicians, nurses, therapists, social workers, and pharmacists, working collaboratively to address the various needs of patients. Each healthcare professional brings unique expertise and perspectives, contributing to a more comprehensive understanding of the patient's condition and tailoring treatment plans accordingly.
For example, a patient with a chronic...

Reliability and Validity

Reliability and Validity

Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.
