In clinical trials and other scientific studies, an interim analysis is an analysis of data that is conducted before data collection has been completed. Clinical trials are unusual in that enrollment of subjects is a continual process staggered in time.
The PRISMA flow diagram, depicting the flow of information through the different phases of a systematic review. PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) is an evidence-based minimum set of items aimed at helping scientific authors to report a wide array of systematic reviews and meta-analyses, primarily used to assess the benefits and harms of a health care ...
The main product of the CONSORT Group is the CONSORT Statement, [1] which is an evidence-based, minimum set of recommendations for reporting randomized trials.It offers a standard way for authors to prepare reports of trial findings, facilitating their complete and transparent reporting, reducing the influence of bias on their results, and aiding their critical appraisal and interpretation.
A systematic review is a scholarly synthesis of the evidence on a clearly presented topic using critical methods to identify, define and assess research on the topic. [1] A systematic review extracts and interprets data from published studies on the topic (in the scientific literature), then analyzes, describes, critically appraises and summarizes interpretations into a refined evidence-based ...
In medicine, a clinical study report (CSR) on a clinical trial is a document, typically very long, providing much detail about the methods and results of a trial. A CSR is a scientific document addressing efficacy and safety, not a sales or marketing tool; its content is similar to that of a peer-reviewed academic paper. [ 1 ]
Technical reports are often prepared for sponsors of research projects. Another case where a technical report may be produced is when more information is produced for an academic paper than is acceptable or feasible to publish in a peer-reviewed publication; examples of this include in-depth experimental details, additional results, or the ...
An example would be switch from a superiority to a non-inferiority design. Group sequential Sample size, by a set interval at a time. Sample sizes can be changed. These trials usually change the sample size by adding or removing set-blocks of patients such as adding 20 patients at a time, and then re-evaluating.
ITT analysis is intended to avoid various misleading artifacts that can arise in intervention research such as non-random attrition of participants from the study or crossover. ITT is also simpler than other forms of study design and analysis, because it does not require observation of compliance status for units assigned to different ...
