Positive predictive value - the probability that a person with a positive test is a true positive (i.e. does have the disease). Using data from table 2, the PPV would be 60% (18/30), which essentially means that 6 individuals out of every 10 with a positive tests would actually be truly diseased.

In other words, a positive (negative) value indicates that the biological age of the sample is higher (lower) than expected based on chronological age. Specifically, these measures were defined as residuals (observed minus predicted) resulting from a simple linear regression model that regressed biological age on chronological age.

Sensitivity, specificity, positive predictive value and negative predictive value should be presented. Likelihood ratios can be presented if information about the posttest probability of an outcome based on the decision rule would be helpful.

Positive findings. Strong predictive value. There is the risk of differential exposure assessment due to case-control design and risk of over-fitting the data due to derivation versus validation studies. For cardiac arrest within 48 hours, 4 observational studies and again strong predictive value, with …

To assess the accuracy of DXA testing to predict minimal trauma fracture, the aim was to report the sensitivity, specificity, negative and positive predictive values (NPV, PPV), and likelihood ratios of the tests with corresponding 95% confidence intervals (CIs).

Positive and Negative Predictive Value
We don't use it in asymptomatic infants or infants whose symptoms have resolved. Studies have shown its poor positive predictive value and we find that when clinicians get it, they often respond to values that may be mildly elevated in an incorrect way, putting too much emphasis on a result that doesn't really alter the infant's sepsis risk.

A number of cut-offs were considered for risk catagorisation by analsysing the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of various score ranges. Patients can be catagorised into low-risk (Score 3), moderate-risk (score 3.5-4.5) and high-risk (score 5) groups. 83.8% (469/560) of patients in ...

Sensitivity was 90% (84-96%) and negative predictive value was 93%. The mean time for the EBUS TBNA procedure was 24 minutes. In 2006, Herth and colleagues evaluated EBUS-TBNA in patients with lung cancer and a radiographically normal mediastinum; this study showed an unexpected detection rate of mediastinal metastases of 17% in 119 lymph nodes ...
