Table 1 A guide to interpretation of Likelihood Ratio (LR) values (Adapted from Jaeschke, 1994). Legend: LR + = positive likelihood ratio; LR- = negative likelihood ratio

From: Relationship between nerve conduction studies and the Functional Dexterity Test in workers with carpal tunnel syndrome

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.
