Here we look at studies employing chronic variable stress in rodents and explore how sample size was chosen. Of the 385 studies that we analysed, only one reported calculating sample size based on a biologically meaningful effect size and only 25% mention sample size at all.
A companion article where we analyse the relationship between protocols and reported effect size can be found here
