Sensitivity and specificity

This is meta-analysis study calculate the sensitivity and specificity of self-reports of smoking behavior using the biochemical assessments of smoking substances which are formed in the body to validate it. It was done by Donald L. Patrick, Allen Cheadle, Diane C. Thompson, Paula Diehr, Thomas Koepsell, and Susan Kinne. First, the researchers introduced the smoking as the largest preventable cause of mortality and morbidity in USA, and then introduced the importance of using biochemical…

of the dyes, the biopsy site was determined and sent for histological confirmation. Statistical Analysis Chi-square test was used to compare between Toluidine blue, Lugol’s iodine and Acetic acid. Diagnostic efficiency was calculated by sensitivity and specificity test to determine the utility of the test results.…

operating characteristic curves showed that sensitivity was higher for ASB tenderness. For ASB tenderness, 8 articles studying 1164 patients were included. The sensitivity was relatively homogeneous, with a range between 0.87 and 1.00. The specificity ranged between 0.03 and 0.98 indicating high heterogeneity. For LTC, 8 reports studying 961 patients were included. The test had heterogeneous results for sensitivity (range between 0.48 and 1.00) and specificity (range between 0.22 and 0.97)…

Sensitivity refers to finding out how many people test correctly for the specific disorder or disease. Where specificity refers to finding out how many people do not have the specific disorder to disease. In the case of changing from the DSM-IV to the DSM-5; there was an underlying fear of lacking in the area of sensitivity as it pertains to clinical testing. Unfortunately there has been a decrease in sensitivity, however there has been a great increase in specificity. This shows to…

Reference Purpose Study design Sample size & characteristics Key results Major conclusions Validity Herbst de Cortina et al. To determine sensitivity and specificity of dual HIV/Syphilis INSTI Multiplex downward flow immunoassay POC test Cohort study 200 convenience high risk serum samples, 14 of which were already diagnosed with primary Syphilis by PCR. Peruvian men who have sex with men and transgender women. HIV: sens. 100% and speci. 95% Syphilis: sens. 87.4% and speci. 97.0%. Excellent…

caries. 3. Sensitivity Sensitivity of a procedure correctly detects people having the disease in terms of percentage (Pretty, I.A. et al. 2004). It is a procedure that determines the accuracy of any procedure that is its ability to correctly identify true positives (presence of disease). Hence, the device must have a high sensitivity (100% means that every diseased individual has been identified). Low sensitivity means there have been errors such as missed diagnosis. 4. Specificity It is…

DIAGNOSTIC PATHWAY FOR THORACIC MALIGNANCY MALIGNANT PLEURAL MESOTHELIOMA Malignant Pleural Mesothelioma (MPM) is a progressive, terminal disease of the pleural cavity. This tumour can be divided per their histology (2). Epithelioid is the most common mesothelioma while sarcomatoid type is the least common. The biphasic mesothelioma is a combination of the epithelioid and sarcomatoid type. The sarcomatoid mesothelioma is the lest common. Asbestos have been identified as the predominant cause…

PHQ-9 screener was found to have an 80 percent sensitivity and have a 92 percent specificity for the adult population studied. Prior to the work completed by Richardson et al. (2010), the sensitivity and specificity of the PHQ-9 in the adolescent patient population had not been studied (Allgaier et al., 2007). According to Richardson et al. (2010) for the adolescent patient population, the PHQ-9 has a sensitivity of 89.5 percent and a specificity of 94.4 percent (Allgaier et al., 2007). The…

Unhealthy alcohol use is the spectrum from risky consumption to the alcohol use disorder, alcohol abuse and dependence. Screening and brief intervention for those with unhealthy use are among the most effective and cost-effective services that can be delivered in primary care settings. Addressing Unhealthy Alcohol Use in Primary Care is a resource for primary care clinicians who are confronted by patients with these problems daily, and who wish to successfully address these issues in their…

the validity data of the MCMI-III, then to compare the data to other relative literature (including the manual). Axis I outcomes indicate that the sensitivity values are not adequate, meaning that none of the syndrome scales clearly distinguish between true positives and false negatives. Meanwhile the specificity results were better than the sensitivity values with the exception of the Anxiety scale with a value of .57. All over values ranged from .80 to .99 indicating that the MCMI-III is…
