<p><strong>Background and rationale for study: </strong>For the introduction , you can start by west african region in which the co infection is important.&nbsp; You want to provide data for the gap of information about these co infection in female sex workers. Avoid including method in bacground ( this cross-sectionnal study). The objective is to determine prevalence and factors associated with hepatitis B and C. it’s no necessary to put HBs antigen and HCV antibodies.</p><p><strong>Appropriateness of methods: </strong>You have a part in the introduction that you have to bring back here. The vaginal swab is to research what in your study? blood is taken for serological analysis (introduction). What is the study period? Do you already have two groups formed for the analysis (HIV + and -)? we are looking for an association between the independent variables (risk factors) and the results (HVB and C). the last part to review.</p><p><strong>Presentation of results: </strong>Your results are good but by improving the method, we will understand each other. It is the prevalence of Hepatitis B and Hepatitis C that we want. These are the outcomes so you are looking for associated factors between the outcomes??? keep it simple in presenting the results. You have the prevalence, you have the factors associated with Hepatitis B and those associated with Hepatitis C</p><p><strong>Conclusions and interpretations of results : </strong>Bonne conclusion mais il fallait en introduction donner la prévalence au Mali et faire ici le lien avec un programme particulier à mettre pour ce groupe. Dans ton étude la prévalence des hépatites est faible chez les VIH+. Je te conseille d’éviter de faire deux groupes de comparaison qui vont te créer des problèmes en interprétation.</p><p><strong>Public health significance: </strong>This study will contribute to the improvement of public health. It addresses an important health issue. The recommendations do not follow from the results of the study.</p><p><strong>Overall clarity of the abstract : </strong>We not have a logical sequence within the sections . Review the method, results and conclusion</p>
