Literature search
We performed a detailed systematic search through both medical and nursing databases (PUBMED (MEDLINE), SCOPUS, SCIENCE DIRECT, EBSCO, CNKI, XUESHU and COCHRANE DATABASE) to identify related clinical trials in relation to mucosal damaged induced by paraquat between 2000 to December 2020. Our searches explored the keywords (paraquat, paraquat induced oral mucositis, paraquat tongue, oral care, mucosal injury). The population, intervention, comparison, outcome (PICO) model was used to develop inclusion criteria and search terms per intervention. Population focused on patients who presented with symptoms of oral mucositis after paraquat ingestion. Intervention highlighted the different agents and modes of intervention that were applied in the different trials and a comparison of the management received by the control group and a lack thereof. Outcome was based on improved healing/recovery time.
