(A) Sensitivity and specificity of the AL Home Test RDI-AL compared to polysomnography AHI. (B) Sensitivity and specificity of the AL Home Test RDI-AL compared to AL Lab Test RDI-AL.

PPV, positive predictive value; NPV, negative predictive value; LR (+), positive likelihood ratio; LR (-), negative likelihood ratio. AHI/RDI-AL are presented as events/hour. Sensitivity, specificity, PPV and NPV are presented as percent.
