Each doubling of production generally yields a cut of one-fifth in unit cost per plane.
Jacobson and Truax (1991) formula to distinguish functional and dysfunctional population yielded a cut-off of 16.92 using Spanish normative data (Sanz & Vazquez, 2011).
Receiver operator characteristic analysis used to separate methylated cases into two prognostic groups yielded a cut-off of 29.4% with 71.4% sensitivity and 63% specificity (ROC area 0.759 P=0.001).
Our results for the most commonly used 'probable' dichotomisation level, which yielded a cut-off of approximately 90% in epidemiological samples, were almost identical to those reported by Mathai and colleagues [ 5].
ROC analysis of SUVmax with TOF 30 and 90 min p.i. yielded a cut-off value of 4.5 and 4.7, respectively with a sensitivity and specificity of 89 % and 100%and91 91 % and 100 %, respectively.
For example, assume a cut yielded a lift of 3, then both confidence thresholds would consider this cut significant and generate a new feature accordingly.
Due to the insufficient evidence from both sides, current studies have not yet yielded a clear-cut picture of the miR-29a-3p dysregulandon and its prognostic value in CRC.
ROC analysis yielded an optimal cut-off of 3.37 for the T/N ratio of 18F-FAMT PET to differentiate between HGGs and LGGs (sensitivity 81%, specificity 67%, accuracy 76%, area under the ROC curve 0.776).
Construction of a ROC curve yielded an optimal cut-off value of the HRCT score of 210 which was determined for prediction of survival at day 60 with 71% sensitivity and 72% specificity (AUC, 0.71; 95% CI 0.61 to 0.82) and for prediction of survival at day 180 with 71% sensitivity and 76% specificity (AUC, 0.73; 95% CI 0.62 to 0.84) (figure 3).
Using 50 μg/g as cut off yielded a sensitivity of 73% and a specificity of 93% with good positive and negative likelihood ratios (10.8 and 0.29, respectively).
