Prospective clinical research is a research conducted by researchers according to the requirements of topic selection and design. It is characterized by clear research purpose, careful research plan, reasonable observation indexes and detailed records of clinical data in strict accordance with design requirements. By sorting out, summarizing, counting and analyzing these data, we can draw some conclusions.
Prospective analysis of medical paper writing is scientific and reliable, but it is difficult. The key is to make a good research plan. In order to sum up experience, find out laws and guide practical research.
Retrospective analysis generally adopts random sampling method to determine the scope and duration of cases to be analyzed, so as to make the observation conditions, case diagnosis standards, case collection standards and curative effect judgment standards consistent and minimize errors. Although retrospective analysis is not as scientific as other research methods, case data are relatively easy to obtain.
Advantages of retrospective research
I suggest you publish some research on goals, forecasts and grades, which is the third kind of research I mentioned earlier. You can consult the latest literature, understand the latest prediction models and goals, and change your mind. For example, this article: CNS score predicts the prognosis of patients with non-small cell lung cancer who use Pamzumab.
Then, can we think about whether this score can be changed into other scores? Because there are many scoring systems, if this scoring system is not so good, can it be improved by itself? It has done non-small cell lung cancer, and I can replace it with other small cell lung cancer and other tumors.
It uses Pammonoclonal antibody, so can it be replaced with other monoclonal antibodies? Of course, these are just my own ideas, which may not be feasible. What I want to say is that you just need to read a lot of literature and see what can change your mind and become your own research.
After reading the topic selection skills of retrospective research, are you already eager to think about your own article! But I am not familiar with the specific research design and statistical analysis methods of retrospective research, so please come here.
