To compute an adjusted odds ratio, simply fit a logistic regression model. The outcome variable is the 0-1 variable which represents case or control status. The independent variables include a particular SNP variable, as well as all the demographic variable. The odds ratio that you get for the SNP variable shows the effect of that SNP on cancer status, after adjusting for all the demographic variables.
To calculate an adjusted odds ratio in a logistic regression model, you would first run the regression analysis to obtain the coefficients for each predictor variable. Then, exponentiate these coefficients to get the adjusted odds ratio, which reflects the change in odds of the outcome for a one-unit change in the predictor variable while holding other variables constant.

If the ratio of boys to girls in a class is 5 to 8 and there are 40 girls how many boys are in the class?
Since the ratio of boys to girls is 5 to 8, the total ratio parts is 5 + 8 = 13. To find how many boys are in the class, divide the total number of girls (40) by the total parts of the ratio (13), then multiply by the number of boys parts (5). Thus, there are 15 boys in the class.
What are the odds of a fan catching 2 foul balls in one game?
The odds of a fan catching one foul ball during a game are very low, estimated at around 1 in 1,000. Therefore, the odds of catching two foul balls in one game would be even more rare, likely around 1 in 1,000,000 or lower. It would require exceptional luck and positioning within the stadium.

Adjusted odds ratio?
adjusted odds ratios are the odds of a dichotomous event being true adjusted for or controlling for other possible contributions from other variables in the model.
What is adjusted odds ratio?
As adjusted odds ratio is defined as "In a multiple logistic regression model where the response variable is the presence or absence of a disease, an odds ratio for a binomial exposure variable is an adjusted odds ratio for the levels of all other risk factors included in a multivariable model." Simply put, it is a measure of association between an exposure and an outcome.
How do you interpret the adjusted odds ratio?
The best way to interpret an adjusted odds ratio is to measure its exposure and outcome. For precision, typically a 95 percent confidence interval is used for interpretation.
Difference between adjusted and unadjusted odds ratio?
An odds ratio is the difference between the number of times that something happens and does not happen. An unadjusted odds ratio is a guess between what could or could not happen.
What is the difference between a crude odds ration and an adjusted odds ratio?
Odds ratio (AD/BC) is the ratio between number of times that something happens and does not happen. Crude odds ratio is the ratio that is not stratified (ex. by age). Adjusted odds ratio is a stratified odds ratio. If the odds ratio equals one, then there is no association, and null hypothesis shall be accepted. If one is included into confidence interval, then it is possible that odds ratio equals one, and it is not statistically significant. If stratified odds ratios are about the same, or there are no significant differences, the odds ratios are combined into one common odds summary estimate of two stratum specific ORs using Mantel-Haenszel and/or Cohran's tests, or multivariable analysis.

What is Crude odds ratio?
The crude odds ratio is a statistical measure that quantifies the strength of association between an exposure and an outcome in a study without adjusting for any other factors. It is calculated by dividing the odds of the outcome occurring in the exposed group by the odds of the outcome occurring in the unexposed group.
