The comparisons of predictive values in paired designs do not consider the dependence between predictive values.
Unfortunately, it is often difficult to distinguish between the prognostic and predictive values of these proposed markers and independent validations are frequently lacking.
Moreover, since ERα, FOXA1 and GATA-3 show an intrinsic high correlation between themselves, the prognostic and predictive values of these markers may simply reflect this high expression association and the described biological interactions.
While PSIs have been shown to perform well as screening tools from an epidemiological perspective (overidentification and few false-negatives), problems related to high false-positive rates exist, with most validation studies reporting positive predictive values of between 43% and >90%.
In addition, this study analyzed the sensitivity, specificity, and positive and negative predictive values of agreement between retrospectively-reported headaches experienced at least every other day, frequent medication, and prospective information recorded in headache diaries.
The predictive values of node status between SLNB + USALNB and SLNB alone were compared.
Rodriguez-Novoa et al. analyzed a total of 245 HIV patients and found a good correlation between HLA-B*5701 HLA-B*5701negandve and positive predictive values of 100% and 93%, respectively).
It also produces posterior predictive values of Q for geographic areas located in between and around the individual data points.
Mortality predictive values of APP.
Furthermore, the relative risk of death at day 28 of each threshold level was evaluated to further differentiate between the predictive value of each threshold level.
