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.

Can a country's infant mortality rate be higher than its crude birth rate?
yes
Why the crude mortality rate is lower in haiti than in the US?
The crude mortality rate in Haiti may be lower than in the US due to differences in age demographics, prevalence of chronic diseases, access to healthcare, and health infrastructure. Haiti has a younger population on average, which may result in a lower crude mortality rate. However, the quality of healthcare services in Haiti is generally poorer compared to the US, and there may be underreporting of deaths in Haiti.
Define Mortality rate?
the ratio of death in an area to the population of the area
What is odds ratio?
A crude odds ratio is the probability that a case preceeded the control in regard to exposure and history.
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.
Why do US has a high crude mortality rate compared to Haiti crude mortality rate in the year 2000?
Because of different age-structures of the two populations. In the US, there is a higher proportion of old persons, while in Haiti, there is a higher proportion of young persons. This difference in age structures means that the number of persons who die per unit of time will be higher in the country with a higher proportion of old persons. To avoid this problem, one should use age-standardized mortality rates.
What is the mortality rate of mad cow disease in the world?

What is the formula of maternal mortality ratio?
