What Does Ci Mean in Pharmacy

Abbrev for CONFIDENCE INTERVAL.

What does CI stand for in medical research?

Confidence interval A narrow CI indicates a more precise estimate (for example, if a large number of patients have been studied). The CI is usually stated as ‘95% CI’, which means that the range of values has a 95 in a 100 chance of including the ‘true’ value.

How do you find CI?

Multiply z* times σ and divide that by the square root of n. This calculation gives you the margin of error. Take x̄ plus or minus the margin of error to obtain the CI. The lower end of the CI is x̄ minus the margin of error, whereas the upper end of the CI is x̄ plus the margin of error.
