The flow diagram is titled “Identification of studies via databases and registers”. It is organized vertically into three stages labeled “Identification”, “Screening”, and “Included”, shown along the left side. Rectangular boxes connected by arrows describe the selection process from initial records to final included studies. In the Identification stage, the first text box reads “Records identified from: Databases (n equals 120). Registers (n equals 0)”. An arrow from this text box points right to a second text box labeled “Records removed before screening. Duplicate records removed (n equals 59). Records marked as ineligible by automation tools (n equals 0). Records removed for other reasons (n equals 0)”. A downward arrow from the first text box leads to the next stage. In the Screening stage, the third text box reads “Records screened (n equals 60)”. An arrow from this text box points right to a fourth text box labeled “Records excluded (based on title and abstract) (n equals 17)”. A downward arrow from the third text box leads to the fifth text box labeled “Reports sought for retrieval (n equals 43)”. An arrow from this text box points right to a sixth text box labeled “Reports not retrieved (n equals 1)”. A downward arrow leads to the seventh text box labeled “Reports assessed for eligibility (n equals 42)”. An arrow from this text box points right to an eighth text box labeled “Reports excluded: 27. ‘Coach’ was instructing (n equals 21). Article contained no primary data (n equals 6)”. In the Included stage, a downward arrow from the seventh text box leads to the final text box labeled “Studies included in review (n equals 16)”.PRISMA flow diagram of the screening process
