Diagnostic tests: how to estimate the positive predictive value [PDF]

Neuro-Oncology Practice, 2015
Abstract When a patient receives a positive test result from a diagnostic test they assume they have the disease. However, the positive predictive value (PPV), ie the probability that they have the disease given a positive test result, is rarely equal to one.

The predictive value of prenatal cell-free DNA testing for rare autosomal trisomies: a systematic review and meta-analysis

American Journal of Obstetrics and Gynecology, 2022
Objective: The diagnostic accuracy of cell-free fetal DNA in screening for rare autosomal trisomies is uncertain. We conducted a systematic review and meta-analysis aiming to determine the predictive value of cell-free DNA in screening for rare autosomal

Drug Challenge Tests With General Anesthetics: Predictive Value of Skin Tests

Journal of investigational allergology & clinical immunology, 2019
Background: The study of perioperative drug reactions remains a major challenge for both diagnosis and therapy. The lack of a standard assessment of allergy to general anesthetics and of data establishing the true value of skin tests for most drugs used ...

A prospective validation and comparison of three multivariate models for prediction of difficult intubation in adult patients

Brazilian Journal of Anesthesiology, 2023
Purpose: Several bedside clinical tests have been proposed to predict difficult tracheal intubation. Unfortunately, when used alone, these tests show less than ideal prediction performance.
