This was honestly really good. Using the same example for all the risk ratios was so helpful. Seeing how it compares.

I have developed my own formula for this purpose: You see ARR is 12% and AR is 30%. I divide ARR/AR; i.e, 12/30 which is 0.4 (40%) which gives me the relative risk reduction and automatically I will understand that the remaining risk is 100-40=60% ! Because the total will not be more or less than 100% and it is always fixed! But actually I appreciate your work because I learned the concept from you!

Hi, in this example, the Absolute Risk for fractures with no intervention was 10%. We know that the intervention has a Relative Risk Reduction of 40%, so that means the risk of fractures with the intervention is reduced by 40% of the total risk. To calculate the Absolute Risk in the intervention group, you subtract 40% of the Absolute risk. In this case, it’s 40% of 10%, or 0.4 of 10%, which is 4%. That leaves you with 10% - 4% = 6% Absolute Risk of fractures in the intervention group.

Help! I am just interested.This is all new to me. In a layman's lamnguage, does 1 - the relative risk reduction (RRR) tell us how effectivve/efficient the intevention/training is??
@nccmt3 жыл бұрын
Hi, thanks for your interest. Relative risk reduction tells you how much an intervention lowers the risk specifically in comparison to the control group. This means relative risk doesn’t tell you how effective the intervention is for all populations, but only relative to the control group. The reason is that it does not account for the individuals’ baseline risk of the outcome in the absence of the intervention. To calculate the Relative Risk Reduction (RRR), you subtract the Relative Risk (RR) from 1, so RRR = 1 - RR. Absolute risk, on the other hand, accounts for baseline risk and is a better and often more conservative estimate of the effectiveness of an intervention.

I wonder how many people looking at the vaccine will be like "oh, ok so relative risk does mean something after all" alot of people out here looking at the lower absolute risk and running with that. Relative risk for smoker who develop lung cancer are 7 times higher than non smoker but the absolute risk is only 3% will develop lung cancer than non smokers.... so 97% chance smokers wont develop lung cancer.. smoke up folks!

5:45 "The intervention group's risk of a fracture will be 40% (RRR) of 10% (Control AR), which means the absolute risk in the intervention group will be 6% (Intervention AR)." Just wanting to point out that this is actually 40% less of 10% ( 10 - (10 * 0.4) = 6 ), not 40% of 10% (which is 4%). Great video however, just clearing this up because it's an already confusing topic.

The 30% figure was calculated based on the hypothetical scenario where in a 300-person control group, 90 experienced fractures, so 90/300 = 30%.
