The answer will depend on whether the confidence interval is one-sided, or two-sided and, if two-sided, whether or not it is symmetrical.
Symmetrical 2-sided: ±0.189
z value=0.44
The critical value of z for a 96 percent confidence interval is approximately 2.05. This value corresponds to the point where the area in each tail of the standard normal distribution is 2 percent, leaving 96 percent in the center. It is typically found using z-tables or statistical software.
z = 0.6903
To calculate a confidence interval (CI) from an odds ratio (OR), you first need the natural logarithm of the OR (ln(OR)) and the standard error (SE) of the ln(OR). The CI can then be derived using the formula: CI = exp(ln(OR) ± Z * SE), where Z is the Z-value corresponding to the desired confidence level (e.g., 1.96 for 95% CI). Finally, exponentiate the lower and upper bounds to obtain the CI for the OR itself.

The Z value is 0.
The value is 0.3055
The critical value of z for a 96 percent confidence interval is approximately 2.05. This value corresponds to the point where the area in each tail of the standard normal distribution is 2 percent, leaving 96 percent in the center. It is typically found using z-tables or statistical software.
