When reviewing medical research, it is important for students to recognize the sort of study (randomized clinical demo, case control study, cohort study, or longitudinal study) employed and whether the study is retrospective or prospective. Understanding the sort of research used and whether it is retrospective or possible will aid a student in deciding a study’s quality in an objective manner. This paper will briefly describe the preceding conditions and then go on to applying these conditions to five medical research study abstracts that I actually will describe in depth while pointing out each study’s potential strengths and disadvantages tehnicki.eubd.edu.ba.
There are four types of studies which you can use in the design of a medical research study, those being a randomized medical trial, case control examine, cohort study, and longitudinal study. A randomized scientific trial study is “a clinical study where volunteer participants with comparable characteristics are randomly assigned to different test groups in order to the efficacy of therapies” (Randomized Clinical Trial, last year, para. 1). A situation control study is epidemiological study used to identify factors which could contribute to a medical illness by comparing those who have the disease or condition of interest (the cases) with those who do not have the disease or current condition of interest (the controls). A cohort study is “a study in which subjects who presently have a certain condition and/or receive a particular treatment are followed as time passes and compared with another group who are not influenced by the condition under investigation” (What is Cohort Research?, 2011, para. 1). A longitudinal study is a study that follows patients over a prolonged period of time. Some sources also explain a longitudinal study as you in which the same patients are examined on two or more situations.
A study can either be retrospective or prospective. Retrospective studies look backwards in time and investigates exposures to suspected danger or protection factors in relation to an result that is established at the start of the research. In contrast, a potential study looks forward in time and watches for outcomes, including the development of a disease, during the study period and relates this to other factors such as suspected danger or protection factor(s).
This study shows evidence that aspirin use correlates with lowered risks of digestive tract cancer and perhaps several other cancers, including prostate and breast cancer. The study method examined associations between long-term daily use of adult strength aspirin (325 mg/day) measuring overall malignancy incidence and incidence of 10 types of malignancy among 69810 men and 76303 women. These men and women, who were relatively elderly, took part in the Cancer Reduction Study.
Since this study is a potential cohort study, it does have several specific pros and cons. Strengths are that there is the probability to study multiple exposures and multiple results in a cohort and uncommon exposures can be studied. Major weaknesses are that it is not possible to determine causal effects and it is easily prone to selection bias. Furthermore, potential cohort studies could be very expensive to perform.
Inside summary, reviewing medical research studies can help maximize a student’s understanding of biostatistics and its applications. Whenever reviewing these studies, it is important for students to understand the sort of study used and the potential pros and cons associated with each study. After this understanding is achieved, a student will be able to question the validity of medical research that he or the lady is reading in a aim manner.
