Blind Procedures

Blind Procedures

Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...

Area of Science:

Evidence-based medicine
Systematic review methodology
Otolaryngology

Background:

Systematic reviews are crucial for evidence-based healthcare decisions.
Prioritizing research topics ensures efficient allocation of resources for new or updated reviews.
Tinnitus research requires a structured approach to identify the most impactful areas for investigation.

Purpose of the Study:

To develop and validate an innovative prioritization process for identifying topics for systematic reviews in tinnitus research.
To establish clear criteria for selecting interventions for future systematic reviews.
To streamline the identification of high-priority areas within tinnitus research.

Main Methods:

A two-stage prioritization process was employed.
Stage one involved a scoping review to assess the availability of randomized controlled trial (RCT) evidence.
Stage two used pre-defined primary and secondary criteria to rank interventions for systematic review.

Main Results:

The process identified three high-priority interventions for systematic review: sound therapy (amplification devices/sound generators), betahistine, and cognitive behavioral therapy.
Secondary priorities included Ginkgo biloba, anxiolytics, hypnotics, antiepileptics, and neuromodulation.
The methodology was tested using subjective tinnitus and the Cochrane systematic review platform.

Conclusions:

A robust process was successfully developed to identify priority areas for Cochrane systematic reviews on tinnitus interventions.
The developed prioritization technique is adaptable and can be applied to other clinical conditions and systematic review types.
This approach enhances the efficiency and impact of systematic review generation in medical research.
