0%, positive predictive value (PPV) was 97% and negative predictive value
(NPV) was 93.
The results show a high sensitivity and specificity with a high negative predictive value
High positive predictive value of MASS means a score of 7 or more of MASS strongly suggests acute appendicitis and negative predictive value
shows that MASS less than 7 is in favor of absence of acute appendicitis in most of the patients, this group of patients can be observed for some time, reassessed, further investigated and then can be operated upon or discharged.
In the present study, amongst all individual diagnostic tests, C-reactive protein had the highest sensitivity and negative predictive value
However, the specificity and negative predictive value
narrowed within a limited range in these studies.
In a subsequent validation study among 550 additional participants, the negative predictive value
of the sFlt1:PlGF ratio was robust at 99.
Jonathan Lopez: "Sentinel lymph node biopsy in our clinic had a 91% negative predictive value
for local recurrence, nodal recurrence, and disease-specific death.
In this study, for example, screening for DSM-5 alcohol use disorder among adolescents ages 12 through 17 years with a threshold of greater than 3 days with alcohol use in the past year resulted in 99% negative predictive value
and 44% positive predictive value.
Importantly, compared with a cytology-based strategy, the negative predictive value
is quite high for HPV primary screening.
Marwick: CT's negative predictive value
explains its cost effectiveness.
Results: TLC had sensitivity of 75% for group A (proven sepsis) and 76% for group B (probable sepsis); and had a negative predictive value
(NPV) of 80% and 65% respectively.
When used in PET brain scans, the agent showed 98% sensitivity for beta amyloid plaques, with a 96% negative predictive value
