Summarising and validating test accuracy results across multiple studies for use in clinical practice

Following a meta-analysis of test accuracy studies, the translation of summary results into clinical practice is potentially problematic. The sensitivity, specificity and positive (PPV) and negative (NPV) predictive values of a test may differ substantially from the average meta-analysis findings, because of heterogeneity. Clinicians thus need more guidance: given the meta-analysis, is a test l...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Interpretation of cytogenetic results in multiple myeloma for clinical practice

The interpretation of cytogenetic abnormalities in multiple myeloma (MM) is often a challenging task. MM is characterized by several cytogenetic abnormalities that occur at various time points in the disease course. The interpretation of cytogenetic results in MM is complicated by the number and complexity of the abnormalities, the methods used to detect them and the disease stage at which they...
