Table 2
Size of likelihood ratios (LRs) and associated utility of changes in probability 13
| Size of LRs | Utility |
|---|---|
| +LR>10 or –LR<0.1 | Generate large changes from pre to post-test probability |
| +LR 5–10 or –LR 0.1–0.2 | Generate moderate shifts in pre to post-test probability |
| +LR 2–5 or –LR 0.5–0.2 | Generate small changes in pre to post-test probability |
| +LR 1–2 or –LR 0.5-1 | Generate little or no shift in pre to post-test probability |
