Finally, all in all, 96 content was indeed provided for the true purpose of which opinion. Look for Profile 1 getting details of brand new look and you will options method.
Profile step one Flowchart discussing the fresh look and you can alternatives method. Which figure identifies the look and choice for technique for the latest degree one of them story review. Initial, 4359 studies had been understood owing to databases looking; upcoming, 3543 education out-of him or her was basically processed to have headings and you can abstracts; and away from these 3543 knowledge, 160 full-text message posts had been assessed getting qualifications.
