Median
The middle value in an ordered set; with an even number of observations, conventionally the average of the two central values.
How to read it
For five patient reductions of 10%, 20%, 47%, 60% and 80%, the median reduction is 47%. Check sample size, distribution, time point and estimation method.
A common pitfall
It is not everyone’s result or necessarily the mean. Median survival uses survival-analysis methods and accounts for censoring rather than simply ordering all observed times.
