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.

| Outcome | Effect | Evidence | Status / GRADE |
|---|---|---|---|

Miscarriage (Loss of pregnancy before 20 completed weeks of gestation) Metabolomics vs non metabolomics | OR 1.18 [0.77, 1.82] | 3 studies · 869 participants | Low Downgraded: risk of bias |
