Outcome terms were sensitivity, specificity, negative predictive value, NPV, positive predictive value, PPV and accuracy.
The metrics selected to evaluate reporter performance were sensitivity, specificity and diagnostic accuracy.
Conducted were sensitivity analyses of influential parameters, including tritium source, temperature, flow-rate capacity and surface condition.
The overall pooled estimates for the diagnostic value of CT were: sensitivity 93.4 %, specificity 93.3%%, accuracy 93.4 %, PPV 90.3 % and NPV 95.5%[23]3].
The diagnostic accuracy measures used in the analysis were sensitivity, specificity, and likelihood ratio for positive and negative test (LR+ and LR−).
The characteristics of the optimized formaldehyde biosensor were: sensitivity 22 A m−2 M−1, detection limit 32 μM, and linear dynamic range 50 500 μM.
Predictive value of BV for preterm birth before 33 weeks were: sensitivity 12.8%, specificity 95.0%, positive predictive value 35.3%, and negative predictive value 84.3%.
The two primary signal detection variables of interest were sensitivity (the ability to discriminate visual signals from visual noise) and response bias (the tendency to report the presence of a signal, regardless of whether one is present).
The aggregated performance characteristics of CT for ischemia in SBO were sensitivity of 83% (range, 63 100%), specificity of 92% (range, 61 100%), PPV of 79% (range, 69 100%), and NPV of 93% (range, 33.3 100%).
The aggregated performance characteristics of CT for complete obstruction were sensitivity of 92% (range, 81 100%), specificity of 93% (range, 68 100%), PPV of 91% (range, 84 100%), and NPV of 93% (range, 76 100%).
Main outcome measures were: sensitivity, specificity, positive and negative likelihood ratios of the primary studies, weighted means of these parameters in each comparison (clinical examination, radiography, and ultrasound compared to a reference standard in diagnosing AMS), and summary ROC curves and their Q* points where sensitivity equals specificity.
