The overall performance of the OSNA assay in this study is almost equivalent to the results of two pooled analyses of previous trials in which similar protocols were used in patients who did not receive preoperative systemic therapy (accuracy, 93.6 96.1% sensitivity, 87.9 91.7% specificity, 94.8 97.0% Cserni, 2012; Tamaki, 2012).
Objectives: This study was designed to describe exactly the effects of acute decrease in systemic afterload on the accuracy of Doppler-derived left ventricular rate of pressure rise (LV ΔP/Δt) measurements compared with other routinely used indices of systolic function.
Proposed indirect methods showed reasonable accuracy in systemic citrate load estimation.
In parallel, the search for biomarkers to improve diagnostic accuracy in systemic infections is especially relevant in an ICU setting.
However, as with any technology, systemic biases affect the accuracy of sequencing data and thus the strength of conclusions that can be drawn.
Figures 4A and 4B show that the Q*index was 0.64 and the area under the curve (AUC) 0.68 for brain tumour studies, while the Q*index was 0.80 and the AUC 0.87 for non-brain tumour series, indicating a statistically significant higher level of overall accuracy in systemic tumours (z-statistic 4.354, p < 0.0001).
The studies were evaluated for the effect of sublingual nitroglycerin on coronary artery diameter, evaluable segments, objective and subjective image quality, systemic physiological effects and diagnostic accuracy.
2.26 is the 95% quantile for the t-distribution with 9 d.o.f., since accuracy involves both systemic and random errors.
Forearm venous plethysmography is a well-established method for assessing systemic vascular function, with defined accuracy and reproducibility (Joannides et al. 2006).
We thus applied a narrative synthesis of the effect of sublingual nitroglycerin on coronary artery diameter, evaluable segments, objective and subjective image quality, systemic physiological effects and diagnostic accuracy.
Articles were included based on the following criteria: study domain, patients with suspected or known CAD; index test, CT; evaluation of premedication, nitroglycerin; study results, coronary artery diameter, evaluable segments, objective and subjective (e.g., Likert scale) image quality, systemic physiological effects and diagnostic accuracy.
