This systematic review study will investigate existing documents with search phrases and terms including cooling vests, physiological response, and effect employing Mesh terms or synonyms related to search strategy. Web of Science, PubMed, Scopus, Cochrane Library and Google. This systematic review will be done using the suggested reporting items for systematic review and meta-analysis protocol (PRISMA-P) 2015(18). This protocol has been written based on the PRISMA Protocol Checklist and has been registered in the PROSPERO with the registration number: (CRD42019140820)
- Studies investigate types of CVs.
- Studies that Compare among of CVs.
- Studies investigating the Performance of types of CVs.
- Studies investigating the effect of CVs on physiological responses human body.
- The effect of CVs on perceptual responses human body.
- Studies with the English language.
- Studies investigating perceptual human responses.
- Studies about the effect of personal cooling on thermal manikins.
- Studies investigating the effect of personal cooling on spinal cord injury.
- Studies on the effect of personal cooling on cure infant or other diseases.
- Studies investigating on the modeling of personal cooling without human subjects’ response.
- Studies with non-English language.
The aim of the search is to find both published and unpublished studies. A preliminary search of Pubmed was undertaken to identify articles on this subject. The text words contained in the titles and abstracts of relevant studies, and the Mesh terms used to describe the articles were used to develop a full search strategy (see Appendix 1). If we find other relevant keywords during our primary search, we will include in the search syntax. Also, the included studies reference will be searched for additional studies.
We will search PubMed, Scopus, and Web of Science. Other resources such as conference papers, books, thesis, research reports, and guidelines will also be investigated to find the gray literature. Conference papers will be searched via Scopus database. In order to find more related studies, the reference lists of included papers and the table of contents of key journals on the subject will also be investigated. Studies that were published between 2000 and 2019 will be included.
All searched studies will be exported in the EndNote software then duplicated records will be removed. Two informed authors will investigate them separately in order to identify relevant studies according to title, abstract and keywords. Then reviewers will investigate identified articles based on inclusion criteria for their full-text investigation. The included study lists of two reviewers will be compared and cases of disagreements will be resolved through discussion and consensus. In the case of unresolved disagreements between two reviewers, the entire research team will make the decision about the inclusion or exclusion of a study. More potential relevant documents will be identified through the extracted documents references and key journals. Also guidelines, standards and documents introducing models or tools will be reviewed to find more relevant factors.
Using EndNote software identified studies will be classified and screened. Two reviewer authors will investigate them separately in order to identify relevant studies according to title, abstract and keywords. Then reviewers will investigate identified articles based on inclusion criteria for their full-text investigation. The included study lists of two reviewers will be compared and cases of disagreements will be resolved through discussion and consensus. In the case of unresolved disagreements between two reviewers, the entire research team will make the decision about the inclusion or exclusion of a study.
ASSESSMENT OF METHODOLOGICAL QUALITY
The methodological quality of the included documents will be assessed using a researcher-made quality assessment form. Two reviewers will evaluate each document quality using a checklist. In case disagreements were not resolved, a third reviewer would reassess the manuscripts.
After completing the process of searching literature, the full text of studies will be given to the reviewers. Then two data extraction forms will be used for data extraction. The first form will include general information of the included articles such as first author name, publication year, document type, study location, the methodology of research and findings. Another form will be used to identify the details of indicators and domains. The corresponding author will be contacted by email and ask authors to give full texts or data, in case of failing to access them. In the case of inaccessibility to the full text of articles, they will be excluded from the study.
