2.3 Selection of studies
Selection of studies was done using four stages and based on PRISMA
flow-diagram (39). In the first stage, identification, studies
identified through database searching were collated in ENDNOTE software,
and duplicates were omitted. In the second stage, two reviewers
independently screened the titles and abstracts and removed irrelevant
articles.
In the third stage, the full-text articles were independently evaluated
for eligibility by the reviewers. In the fourth phase, the two reviewers
(MZ and ZK) compared and verified their findings. Any disagreement was
resolved either through discussion or involving a third reviewer (YGH).
Information such as author, year, study design, m-health intervention,
outcome, and results were retrieved.
