Key result
Sleep stage classification using a load-cell-installed bed demonstrated 92.5% epoch-by-epoch agreement and a Cohen's kappa of 0.62 compared to standard polysomnography.
Why the study?

Does a load-cell-installed bed accurately estimate slow-wave sleep compared to polysomnography?
Effect estimate: Cohen's kappa 0.62
A load-cell-installed bed provides a non-constrained method for estimating slow-wave sleep with substantial agreement to standard polysomnography.
Choi et al. (2009) studied Sleep. Load-cell-installed bed vs. Polysomnography (PSG) was evaluated on Epoch-by-epoch agreement with PSG (Cohen's kappa 0.62). Sleep stage classification using a load-cell-installed bed demonstrated 92.5% epoch-by-epoch agreement and a Cohen's kappa of 0.62 compared to standard polysomnography.
