What does MHID mean in UNCLASSIFIED

MHID stands for Mantel Haenszel Incidence Difference and it is a statistical method used to assess the incidence of disease or other events between two groups in an observational study.

The MHID statistic uses contingency tables and estimates the differences in incidence between two groups by calculating odds ratios from these tables. It then uses these odds ratios to calculate a measure of association between the exposures and outcomes studied.

Researchers typically use the MHID statistic when they are conducting observational studies in order to evaluate potential associations between exposures and outcomes. It is especially useful when assessing results from cross-sectional studies that compare different levels of exposure with different levels of outcome among different groups.

One limitation with using the MHID statistic is that it can only provide relative comparisons and cannot provide absolute measures of association due to its reliance on raw data from contingency tables. Additionally, since it relies solely on observations rather than randomized control trials, results may not always reflect true causal relationships between variables studied

Compared to other methods such as randomized control trials, using the MHID statistic has many advantages such as being faster and cheaper as well as providing more direct evidence as it relies on observed data rather than estimated values from population data analysis. Moreover, researchers can adjust for potential confounders which could affect results, making interpretation easier and more reliable.
