Table 1 A guide to interpretation of Likelihood Ratio (LR) values (Adapted from Jaeschke, 1994). Legend: LR + = positive likelihood ratio; LR- = negative likelihood ratio
LR+ | LR- | Interpretation |
|---|---|---|
> 10 | < 0.1 | Generates large and often conclusive shifts in probability. |
5–10 | 0.1–0.2 | Generates moderate shifts in probability. |
2–5 | 0.2–0.5 | Generates small, but sometimes important, shifts in probability. |
1–2 | 0.5–1 | Alters the probability to a small, and rarely significant, degree. |
