Rahul nice videos. I am working in cancer epi, and teaching population epidemiology. You did a nice job. If you don´t mind I will recommend your youtubes in case the students would like to hear an alternative way of explanation! Just one comment... in minute 4 you discuss the persons at risk, but you omit the person-time (you just take the number of persons). Why did you not take the time at risk during the 10 years into account in your explanation?

Prevalence. Errbody is involved at x time. Count them all including the RIPs, substract those.
@maryhannah96853 жыл бұрын
i still dont get how you got "6" people at risk of cancer at 5:05, it says "never had cancer" .... shouldn't it be 5 cases of 'at risk for cancer?'
@dilaraesmer3 жыл бұрын
Not having cancer within the specified time does not mean that they are not at risk, it just means that the disease has not yet occurred. I think 6 people were taken for this reason.

Hi Rahul, I am curious why you DIDN'T count the number of person years in your calculation of incidence in this video whereas in your last example (your other video) of incidence you did?

@sabarikrishnanb.b.43508 ай бұрын
There are 4 new cases. So, it should be 4 over 6, right?

Very well simplified, however, I though the denominator for the incidence would have been 5 and not 6 considering that the 6th person developed cancer after the 10 year period...?

If an individual has multiple new cases does that affect the incidence?
@albiner19995 жыл бұрын
Sarah, Greetings. Yes, some conditions such as myocardial infarction, fracture, adverse reactions, etc may have multiple episodes occurring within the same individual. First, for us to consider multiple episodes within an individual, he/she must have full recovery between episodes. Once this criteria is fulfilled, the usual way of calculation is via person-duration or person-years. For instance, 18 myocardial infarctions (MIs) were experienced among 157 individuals followed up each for two years. In that arm, during a period of 314 person-years of follow-up, the rate is (18 divided by 314) = 0.057 per person-year or 5.7 per 100 person-years. The 18 MIs arose through 12 patients having single MIs and 3 patients each having 2 MI. So, to your query, if there are multiple cases occurring, yes - the incidence would go up.

people that had cancer cannot be at risk because they already have it now. i don't get it how he counted them with the people at risk that's confusing
@chinmayeechavan57242 жыл бұрын
It's the time frame in which we are counting the risk, ....these people had the risk and caught the disease , both within the the time considered , .......in case if you say those who caught the disease in the given time (who previously were at risk before acquiring the disease) shouldn't be counted ...then you will end up counting only those people who are not affected by the disease , which in this example will be 1 ..and that would be a different entity

@@sanadbenali6993 Greetings. Risk means probability of acquiring the condition and importantly must not have the condition in question at the start of the time frame. Six individuals at the start of the time frame, did not have the condition YET, so these six is calculated as the denominator irrespective of whether they end up with the condition.
