Title & Introduction
* Research titles can make the difference between reading the whole article or just reading the abstract of it, it is what might catch the interest of the reader or not. Researchers have to make sure to come up with a title that is catchy but at the same represent the objective of the investigation. The title of this investigation really shows the content of the research, explaining all the factors the green tea does for the body. It also have a positive tone, meaning that as soon as you read the title you know the green tea is good for you, and that it might help you if you suffer any of the problems stated in the title. * Providing with background information is important, because the readers are most likely to be unfamiliar with the topic. They present the positive aspects of the green tea extract in the tittle, and also a good overview of the research in the abstract. They explain key issues, including key terms in parenthesis, and an “abbreviations” part where it shows you all the key words about the investigation. All the dates, events and different factors that affected the research are well presented, as well as the people and authorities related to the study. Last but not least, references with additional links that might lead the reader to additional resources if interested. * The world as we know it today is really concerned with human health, and this study shows how green tea might be a positive factor in the aid of numerous problems many people are facing today. Green tea extract can be an excellent choice for people who cannot afford expensive treatments, but still need to take some medication to aid these problems. Having options and the right to choose is important for everybody, and studies like this can help the population have a healthier lifestyle making the right choices. Research Question / Hypothesis
* What are the effects of green tea extract in obese, hypertensive patients? * The supplementation with green tea extract improves insulin resistance and associated cardiovascular risk factors in obese, hypertensive patients because of the high amount of catechins found in it. Methods Section
* The population would be the 183 patients with hypertension registered for the study. The sample would be the 56 patients (28 men, 28 women) selected. * A stratified sampling was used, where both groups were fairly represented (males/females). * There was a non-random selection of the subjects for the study, following certain inclusion factors, but there was a random placement of the sample in the two different groups.
