Full Characterisation of Heroin Samples Using Infrared Spectroscopy and Multivariate Calibration
the collected spectral data and PLS modelling. These models were able to identify heroin correctly for 96% of the samples of the external test set with precision, specificity and sensitivity values of ...
The 2021 WHO catalogue of complex mutations associated with drug resistance: A genotypic analysis.
from 45 countries. For each mutation, a contingency table of binary phenotypes and presence or absence of the mutation computed positive predictive value, and Fisher’s exact tests generated odds ratios ...
Nursing home residents with suspected urinary tract infections: a diagnostic accuracy study
The combined nitrite and leucocyte esterase urine dipstick test (one or both positive) had a 96.0% negative predictive value (95% CI: 80.5-99.3%). The sensitivity of a positive CRP test (≥ 5 mg/L) was ...
Retrospective evaluation of routine whole genome sequencing of Mycobacterium tuberculosis at the Belgian National Reference Center, 2019.
100% (pyrazinamide, PZA). The negative predictive value was above 95% for these four first-line drugs. A positive predictive value of 100% was calculated for INH and PZA, 80% for RIF and 45% for EMB. ...
Comparing health insurance data and health interview survey data for ascertaining chronic disease prevalence in Belgium.
both data sources were compared. Agreement was measured using sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) assuming BHIS data as gold standard. Kappa ...
Prediction of Susceptibility to First-Line Tuberculosis Drugs by DNA Sequencing
other drugs or if they contained mutations of unknown association in genes that affect susceptibility to the other drugs. We simulated the way in which the negative predictive value changed with the ...
Accuracy of combinations of visual inspection using acetic acid or lugol iodine to detect cervical precancer: a meta-analysis.
were computed. Clinical utility was assessed from the positive predictive value (PPV) and the complement of the negative predictive value (cNPV). MAIN RESULTS: We included 23 studies comprising 101 273 ...

Decision criteria for MALDI-TOF MS-based identification of filamentous fungi using commercial and in-house reference databases
identification of 87.41% (in-house database) and 35.15% (Bruker database) of isolates, with a positive predictive value (PPV) of 1 at the genus level for both databases as well as 0.89 PPV (in-house database) and ...
