Nitrogen mineralization: a review and meta‐analysis of the predictive value of soil tests
, 2011Accurate estimation of mineralizable nitrogen (N) from soil organic matter is essential to improve fertilizer management in agricultural systems. Mineralizable N refers to the amount of N in soil that is released during a certain period (ranging from 1 ...

Re: Predictive Value of a Positive Test
JAMA: The Journal of the American Medical Association, 1986To the Editor.— Billings and Bernstein1reported findings of a survey conducted among physicians, house officers, and medical students to assess the performance of clinicians at calculating the predictive value of a positive test result. The following question, modified from Casscells et al2was posed to 30 respondents: "If a test to detect a disease ...

Predictive value of coagulation tests in arterial thrombosis
La Ricerca in Clinica e in Laboratorio, 1988In five large-scale prospective studies the predictive value of hemostatic parameters indicating the occurrence of arterial thrombotic diseases has been estimated in healthy individuals. All the studies have consistently found a statistically significant association between hyperfibrinogenemia and arterial thrombotic diseases. In two studies, increased

The predictive value of microbiologic diagnostic tests if asymptomatic carriers are present
Statistics in Medicine, 2002If a proper gold standard is not available, then the predictive value of a test cannot be estimated. In this paper the concept of etiologic predictive value (EPV) is introduced.

Predictive value of blood clotting tests in cardiac surgical patients.
Annals of Thoracic Surgery, 1995This study prospectively evaluated numerous tests of clotting function in 897 consecutive adult cardiac surgical patients over 18 months. This included coronary operation, valve replacement, and reoperative patients. The tests included activated clotting

Predictive Value and Efficiency of Laboratory Testing
Pediatric Clinics of North America, 1980Literature on determining reference values and reference intervals on "normal" or "healthy" individuals is abundant. It is impossible, however, to evaluate a data set of reference values and select a suitable reference interval that will be meaningful for the practice of medicine.

The predictive value of rodent carcinogenicity tests in the evaluation of human risks.
Annual Review of Pharmacology and Toxicology, 1979In the last fifteen years various authors have estimated that from about 70% to 90% of all human cancer cases can be attributed to environmental causes (4, 19, 20, 61).
