How to meta-analysis when results are both in hours and days I'm doing a meta-analysis studing lenght of stay after a particular protocol.
However, some studies report their results (meand and SD) in hours and others in days.
How can i change results in days to hours?

The overarching question is: is the length of stay approximately normally distributed? If so:

*

*Select a metric, such as hours, to measure the data.

*Convert all values in days to hours by multiplying both the mean and standard deviation by 24.

*Determine the standard error (SE) by dividing the standard deviation (SD) by the square root of the sample size (n).

*Use inverse variance methods to meta-analyze the means and SEs.

If you select days as a metric, you have to divide means (SDs) in hours by 24.
