Most Covid 19 research do not have a large sample size (smaller than 100, some even smaller than 50), which is understandable since it is a very new field of research (less than one year), and generally, small sample sizes mean that it is difficult to draw an accurate conclusion, given that, to extent are those research accurate or reliable?
Sounds great! Looking forward to knowing the outcomes of your research. Good luck
Any research that takes long period of time and large sample of cases should be promising.
I am really surprised when I saw some empirical papers published in good journals. how they managed to get data during lockdowns. meanwhile, a small sample is another reason to probe the outcomes of such research
You brought up good points. They get data from patients who are admitted to hospitals and volunteers of course. Probably research with small samples will have a follow up in future when more samples are obtained. We shall see.
It is difficult to tell as the policy of almost all journals in the past couple of months was to publish anything related to COVID 19 immediately.
Agreed! Too short a time span here, but, not like we really have a choice here too, so probably some journals might be retracted or have to be edited or revised in future in my opinion.
Yes Hermann Gruenwald I could not find any clear answer for a single question even when it come to wearing the face mask.

Dear Researcher,
Hello. You have asked a question which is very much relevant in the current era.
Most COVID-19 researches are based on low number of samples. Moreover, these are based on secondary data. More importantly these researches are following a refining approach i.e. they are aiming to refine the existing knowledge about pandemics. These researches, in most cases are not following an applied approach. Thus, the results of these researches when applied in reality are not fetching much result. Hence, we can see an increase in the number of COVID-19 cases, at least that is the case in India.
So, I am being forced to come to the conclusion that most COVID-19 related researches are not very accurate or reliable.
Thank you.
Best regards,

I agree with that most of the research regarding COVID-19 is not reliable. And nothing clear to this moment, we need clear answers based on research and facts.
Thank you for your explanation. My thoughts exactly. Some peer reviewed studies only have 30 samples, for instance, the study on Covid 19 antibodies decline after 8 weeks in individuals who were infected by Covid 19 before. On the other side of the story, it is impossible to wait for years and obtain sufficient sample size, if any, prior to conducting a research since it will be too late by then.
Dear Michael Halim
Currently we are doing a trail on Effectiveness of Pulmonary Rehabilitation on Covid patients under supervision of Department of Rehabilitation Medicine. We are taking data on admission, and then consecutive 3 weeks. Patients usually remains in in-patient department for about 2 weeks. So we have to take 1-2 weeks post-covid follow up data. We are the primary physicians who are responsible for patients management and we are taking data. So, lets hope for a better outcome.
