Data extraction, (selection and coding)
Selection of studies:
- Will be decided on according to PICO format.
- All synonyms of search terms will be entered into 3 search engines.
- Final yield will be saved into EndNote.
- Duplicates will beremoved electronically, and by hand,
- Selection criteria will be devised,
- 2 reviewers will independently apply the selection criteria to final library of abstracts,
- 2 reviewers will meet to discuss included and excluded abstracts,
- Discrepancies will be treated by consultation with 3rd party or by obtaining full text of articles,
Coding- Data to be extracted:
- Quality assessment ratings,
- Intervention details e.g. length of treatment, setting etc,
- Comparator details ,
- Outcomes (speech and language, literacy).
Risk of bias (quality) assessment
The Downs and Black quality assessment tool will be applied independently by two researchers. This will affect the planned synthesis by determining the method of anaylses.
Strategy for data synthesis
Unconfirmed at this stage. It is planned that aggregate data will be used in meta-analysis if quality/design of studies allows for this.
Analysis of subgroups or subsets
- Planned to be submitted to appropriate Speech and Language Pathology journal.
- Presentation at Eastern Health research forum.
- Presentation to Research Training Scheme participants.
- Submission to Speech Pathology Australia conference.
