Critical appraisal of an article by nicolosi and fellow researchers

The extensive knowledge gained by these researchers in their respective fields, means they are knowledgeable and legible to conduct the study. Although the title of the article is not clear, it mentions the variables being measured – oral hygiene with 0. 12 chlorhexidine gluconate and VAP. Notably, the research fails to mention the study population in the title. Key aspects of the research have been outlined in the abstract. However, substantial literature supporting the study is included in the introductory part. Additionally, the study framework is not explicitly expressed in the study. The research objective was to determine the effectiveness of tooth brushing accompanied by rinsing the mouth with 0. 12% chlorhexidine in preventing VAP after cardiac surgery. However, no research question or research hypothesis was mentioned in the study.
