You must also describe any procedures that you used to maximise or measure compliance with the interventions order viagra plus 400 mg without prescription. If a drug is being tested order viagra plus 400mg otc, then the generic name, the manufacturer, the doses used and any other information should be included. Clinical assessments Research is never completed … Around the corner lurks another possibility of interview, another book to read, … a document to verify. Most equipment that can be bought off the shelf is well known and can be described with a simple brand name and supplier. However, rare or newly devised equipment will need to be described in more detail. Only ever give a reference to a previous journal article to describe a method if the journal is freely available and if the article describes the method in a comprehensive way. It is sometimes a good idea to say why a particular method or piece of equipment was used and what advantages it had over other similar or more commonly used methods. It is also important to include details of how equipment was calibrated and standardised if more than one piece of equipment was used. A critical issue in reducing bias in any study is the degree of comparability between items of equipment, between observers and within participants. Always give the P value that you used as the critical value to determine statistical significance. This is usually P < 0·05, although values such as P < 0·01 are common if multiple statistical tests are being conducted, and a critical level of P < 0·1 is sometimes used in multivariate modelling. Results can vary if the outcome or exposure variables are analysed as continuous, non-parametric, or categorical data. It is essential that you give as much information as possible about the distribution of your variables and the tests you use because serious bias can arise if the incorrect statistical test is used. In essence, readers need to know exactly how you obtained your results and why you came to the conclusions that you reached. If you used a statistical test that is not simple or well known, a reference to the method and an explanation of why you used it is required. The truth of this proposition will come home to you as you read biomedical writing and discover how easy it is to get the wrong message. Mimi Zeiger4 This section is the most important part of your paper because its function is to give specific answers to the aims that 63 Scientific Writing you stated in the introduction. You should use an interesting sequence of text, tables, and figures to answer the study questions and to tell the story without diversions. It is essential to know your audience and make it clear to them in their own language how your work is an important extension of what has gone before. Although consistency of evidence is critical for ascertaining causation,11 most editors are not keen to publish results that are already thought of as established knowledge. It is important to convince the journal editor, your reviewers, and your readers that your study extends knowledge rather than merely confirms what we already know. The best way to present results is to gradually build up from univariate statistics to describe the characteristics of your study sample, through bivariate analyses to describe relationships between your explanatory and outcome variables, and finally to any multivariate analyses. This section should be quite straightforward and should guide your reader through your own discovery processes. The length of the section should be dictated entirely by how many results you have to present and not by how much you want to say about them.
