though possibly fewer matches. A lower threshold can produce more matches, but some of these matches might be of lesser quality. Business requirements help drive decisions. Results can vary depending on whether you take a conservative or more aggressive approach to defining the cutoff values. ...
Results: We found the extreme value approach had minimal bias when targeting a specificity of 0.995. Using the empirical quantile of the negative controls performed well when targeting a specificity of 0.95. The higher target specificity is preferred for overall test accuracy when...
Although D-dimer is recognized as a reasonable screening tool for VTE, the specificity of D-dimer testing using a conventional cutoff value of 500 mcg/L is particularly poor in patients over 50 years. It's time to use an age-based approach to D-dimer: an age-adjusted D-dimer cutoff -...

Diagnostic usefulness and cutoff value of Schirmer's I test in the Japanese diagnostic criteria of dry eye BACKGROUND: Recently, the diagnostic criteria of dry eye have been tentatively approved in Japan. The aim of this study was to evaluate the diagnostic usef... DANJO,Y - 《Graefes Arch...
And when the optimal cut-off value for S/CO ratio was 21.36, the sensitivity and specificity of HCV RNA positive were 89.90% and 72.73%, respectively. In conclusion, the status of HCV infection can be predicted based on the S/CO ratios of the ELISA assay, which can improve diagnosis and...
It's time to use an age-based approach to D-dimer: an age-adjusted D-dimer cutoff - rather than the conventional 500 mcg/L value - is a better way to rule out VTE in patients over 50 Males and females, 96.1 and 96.0 percent, respectively, had a predicted probability meeting the mini...
the eyes open. The test was performed twice. The timer was stopped if the patient made contact with any part of the room with any part of the body other than the supporting foot, began to hop around, or moved their hand off their hip. The highest value obtained was used in the ...
PSAD cutoff value of 0.20 ng/ml/ml has better discriminatory ability for predicting csPCa and is a significant risk factor for csPCa in multivariate analysis. Conclusion Age, f/tPSA, and PSAD are independent predictors of diagnosing csPCa in patients with negative mpMRI. It is suggested that...
