TABLE 3.

Differing items between PRISMA and PRISMA applied in sports science.

Nº of item in the PRISMA guidelin	Comments
Item 5	Any systematic sport review may register their project in PROSPERO. However, it is not common. Therefore, although it may be suitable, it is not mandatory.
Item 6	PICO(S) search strategy is not used in sports science. Although it is common to use some of the groups from PICO(S), two or three groups are often classified, whereas PICO and PICOS are not commonly used.
Item 17	Flow diagrams may assume any changes in sports science. Therefore, although we have based them on the PRISMA guideline, changes have been computed (Figure 1).
Item 18	In general, tables are more detailed. Therefore, tables assume more columns than the groups used for a search strategy.
