Hi NSRR team, I was under the impression that the majority of the datasets available on NSRR used an updated version of R&K for scoring sleep stages. However, I noticed in Purcell et al's recent publication (Quantifying 11K spindles), they state "All studies used American Academy of Sleep Medicine staging, except the SHHS, which used R&K: here NREM3 and NREM4 were collapsed to a single N3 stage, for consistency with the other studies."

This leads me to believe that CCSHS, CFS, MrOS and SOF are scored using the AASM rules.

Is this correct?

Hi Benjamin,

Are you mainly concerned if whether the studies distinguished N3 from N4? Or are there other aspects you are interested in?

Thanks, Stephanie
