Variable types, study hypothesis, p-value and hypothesis testing
Просмотров 992Год назад
When to do what statistical tests depends on the types and distribution of study variables. And off course, before conducting any significance test, you will need to have a study hypothesis. Then what are the variable types, what is study hypothesis, what are the hypothesis tests and how to interpret a p-value? This short video will discuss these in just 15- minutes!

Fundamentals of mathematical modelling of infectious diseases using COVID-19 as an example
Просмотров 7152 года назад
A simple discussion on the fundamental concepts of mathematical modelling of infectious diseases with a focus on COVID-19. Hope you will find it useful. This is the first of the series on mathematical modelling. In future parts more technical aspects of mathematical modelling including how to do that using statistical software and packages will be shown. Please stay in touch. If you like the vi...

Randomisation in Excel | Epidemiology in Minutes | EpiMinutes 7
Просмотров 3,1 тыс.3 года назад
Randmosiation is an efficient way of allocating study participants in different arms of interventions. By doing this, we try to control for known and unknown confounders, which eventually strengthens the internal validity of a research. In this mini-presentation, I have shown how to do randomisation using Microsoft Excel. I have shown how to do both simple and block randomisation. Also, the vid...
Randomized Controlled Trial | Study designs | Epidemiology in Minutes | EpiMinutes 6
Просмотров 17 тыс.4 года назад
Randomized control trials (RCTs) are the best form of study designs involving primary data collection, especially for finding any association between exposure and outcome. Although it cannot be applied for all exposures or interventions, and can be quite time and resource consuming. In this mini-presentation of EpiMinutes, I am giving a brief overview of the very basics of RCTs, with an example...
Case-control and Cohort Study Designs | Study Designs | Epidemiology in Minutes | EpiMinutes 5
Просмотров 22 тыс.4 года назад
Case-control and cohort study designs are both very useful observational but analytic study designs. The fundamental difference between the two designs is the way you choose study participants. Both the designs can be applied in studies aiming at finding an association between an exposure and an outcome of interest. However, you may need to choose one for various reasons.

Ecological studies can be very useful if we can interpret them with caution. It is a popular study design often used to make comparisons between groups of people on exposures and outcomes of interests. It helps us to find correlations between exposures and outcomes at the population level. Thumbnail: Susmita Roy Resources used: Environmental factors and cancer incidence and mortality in differe...
Case Report and Case Series | Study Designs | Epidemiology in Minutes | EpiMinutes 3
Просмотров 14 тыс.4 года назад
Case reports are the simplest forms of epidemiological studies involving individuals. A group of cases having similar health conditions forms a case series. Both case reports and case series provide an excellent description of a particular health problem. But they cannot test a hypothesis or prove an association between an exposure and outcome. Why? …………………………………………………………………………………………………… Let's ...
Cross-sectional Study | Study Designs | Epidemiology in Minutes | EpiMinutes 2
Просмотров 11 тыс.4 года назад
In cross-sectional studies, we take snapshots of particular health problems in populations at given points in time. Cross-sectional studies are very good at measuring the burden of health problems, which further inform resource allocation and planning. But they may not be as good for finding a causal relationship between an exposure and outcome. Why? ……………………………………………………………………………………………………………. L...

An exceptionally simple, clear, and useful presentation on epidemiological study designs! Epidemiological studies can be classified based on the role of the investigators during the conduction of the study. They can also be grouped based on what the investigators want to achieve or what type of question want to answer. ……………………………………………………………………………………………………………. Let's grab the fundamental concep...
Thank you sir.
You are welcome.
I consider this lecture as very soothing as someone who is very terrible with focusing.. I was too interested in listening, very helpful for me as I study for my exam
Many thanks for your kind and encouraging feedback. Appreciated.
Suggest a book for community medicine
It will depend on where you are based. Thank you.
@@epiminutesbykazi I studying paramedical 2nd year so pls suggest a book for basics
We studied Park's texbook of Preventive and Social Medicine.
Very nice! Would you like to clarify, how did you perform permutation to the bock and to the entire nomber of participants?
Thank you for your question. I did the permutation manually. Given it was a block size of four and combination of two As and two Bs, the six possible permutations could be done manually. For larger sized blocks we might need a software to do that. Even artificial intelligence can help these days. 🙂
Very Nice, but contents of slides are not visible!
Nice presentation and Very good examples, a little slow. Thanks!
Thank you. Yes, I talk a bit slow, which is a feedback I often get. Regards.
Good!
Thank you!
Watching from Uganda this is the first time I get these studies. Blessings upon you 🙏
Many thanks for your nice and encouraging comment from the other part of the world. Best wishes.
Excellent teaching and great video Rahman sir.....

It definitely was. My father in law went there to study medicine. It was before 1947. A graduate from Calcutta Medical College was very much respected.
وين هالفديوهات وقت الدراسة 💔
Thank you for your comment in Arabic. Just translated it into English. JAK.
Great video explanation. Sir please also make a video about effect modification
Very good suggestion. Thank you.
Nicely explained 😊
Thank you
At around the 7:16/18 min, you say (encircling on the slide) that the investigator assigns who gets what treatment. If the investigator assigns who gets what, doesn’t that make it a quasi experimental design? Since the participants are not randomly assigned to the groups. Since you went ahead to mention randomization, I can only assume it’s a language sth and u meant to say something else.
Thank you for your comment. It is the investigators who assign who gets what in an interventional study as opposed to an observational study where investigators have no role on exposure assignment. Now, the investigator may assign exposure/intervention either using randomization or not.
Thankyou sir😊😊😊
Wow❤ Sir.
Thank you sir for great explanation
You are welcome. Best wishes.
Very useful video but that noise is very distracting 😢
Thank you. That's a great comment. I will mute the background music.
@userno695 exactly, its a cringe noise
@@MrGigglesGalore I thought I removed the background music.
It actually made me more concentrated 😂
thank you!!!
My pleasure.
Thank you for this
You are welcome. Kind regards.
Amazing video JazakAllah Khair 😊

Grateful sir for this lecture. My take home here is that a confounder can directly cause the effect, and must be related to the exposure. It sticks better this way. Thank you so much
You are welcome. You are right. Also, it is not on the causal pathway. If you are looking at the association between eating burger and heart disease, then high cholesterol in blood will not be a confounder as it is on the causal pathway.
@@epiminutesbykazi Thank you very much
Thanks alot dear
