The main way the skin prevents pathogens from entering the body is by acting as a barrier. This is because there are many dead skin cells on our skin and this makes it harder for the pathogens to enter the blood stream.

What statistical property make odds ratios the ideal measurement for case control studies?
gregori [183]

Odd ratio's insensitivity to variance makes it ideal for case control study measurements.

What are odds ratios?

An indicator of how closely an incident is linked to exposure is the odds ratio (OR). The odds ratio compares two sets of probabilities: the likelihood that an event will occur in a group that has been exposed vs the likelihood that it will not. Odds ratios are frequently employed in case-control study reporting. The odds ratio aids in determining how likely it is for an exposure to cause a particular occurrence. The likelihood that the event will occur with exposure increases with the size of the odds ratio. Probability ratios below one indicates a lower probability of the event occurring given the exposure.

Odd ratio's insensitivity to variance makes it ideal for case control study measurements. It means that it doesn't get affected if variance is increased or decreased.
