- At the equivalence point, the moles of the reactants are in the exact ratio required by the balanced chemical equation. Unlike the endpoint, the equivalence point is not determined by a visual or instrumental observation. Instead, it is calculated based on the stoichiometry of the reaction.

Odds Ratio = 1: The ratio equals one when the numerator and denominator are equal. This equivalence occurs when the odds of the event occurring in one condition equal the odds of it happening in the other condition.
Aug 13, 2013 · How to interpret odds ratios, confidence intervals and p values with a stepwise progressive approach and a’concept check’ question as each new element is introduced.
Mar 2, 2020 · The odds ratio is the ratio of two odds. ODDS RATIO: Odds Ratio = Odds of Event A / Odds of Event B. For example, we could calculate the odds ratio between picking a red ball and a green ball. The probability of picking a red ball is 4/5 = 0.8. The odds of picking a red ball are (0.8) / 1- (0.8) = 0.8 / 0.2 = 4.
We review the hypotheses for these noninferiority and equivalence research questions, consider power and sample size issues, and discuss how to perform such a test for both binary and survival outcomes. The methods are illustrated on 2 recent studies in hematopoietic cell transplantation.

The standard test is whether the parameter (log odds) equals 0, which corresponds to a test of whether the odds ratio equals 1. Odds ratios typically are reported in a table with 95% CIs. If the 95% CI for an odds ratio does not include 1.0, then the odds ratio is considered to be statistically significant at the 5% level.
The odds ratio is simply the ratio between the following two ratios: The ratio between standard treatment and the new drug for those who died, and the ratio between standard treatment and the new drug for those who survived.
