Findings
The total result we get before these exclusion criteria was formulated
is 42,000 relevant papers. These criteria are used to ensure that the
study results are as accurate and reliable as possible by excluding
participants who may confound or bias the results. We exclude those
materials that are older than 10 years (i.e. papers before 2013 were
discarded), the result from this gives us 17,111 papers. We remove
publications that are not written in English, this reduced the result to
12,800.
Also, we excluded those papers that has only the abstract. These
categories of papers did not give us permission to the full paper, the
remaining papers were 10,005. Similarly, we remove duplicates papers
from the result and the resultant was 905 papers. After removing these
papers, we were left with 16 papers. Our research was based on the
remaining 16 papers.
