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.
