Ungraded means an effect was reported without a GRADE rating; it is not a gap. No studies means the review found nothing to answer the question. The six categories are a display order, not a score.

Summary of findings table ‐ Forward rotation compared to backward rotation for improving sleep and reducing sleepiness among shift workers
Population: shift workers
| Outcome | Effect | Evidence | Status / GRADE |
|---|---|---|---|
Sleep quality off‐shift Summary of findings table ‐ Forward rotation vs backward rotation | no estimate extracted | 62 participants | Very low Downgraded: imprecision |
Sleep length off‐shift Summary of findings table ‐ Forward rotation vs backward rotation | no estimate extracted | 62 participants | Very low Downgraded: risk of bias, imprecision |
Sleepiness during shifts Summary of findings table ‐ Forward rotation vs backward rotation | no estimate extracted | 62 participants | Very low Downgraded: risk of bias, imprecision |
