To determine the cut off category of internal os elastography assessment in selecting high preterm delivery risk patients we have calculated the sensivity, specifity, negative predictive value and positive predictive value.
An OCC statement said the agency does not encourage banks to cut off entire categories of customers, but requires them "to assess the risks posed by customers on a case-by-case basis" and adopt commensurate controls.
That the difference was greater than ours can be partly explained by the limitation of meta-analysis when studies use different volume cut-off categories and adjustment methods and amalgamate studies from different healthcare settings.
Due to the wide variation in the CCI among our patients (range, 0 12; IQR, 0 2), they were divided into good (CCI = 0) and poor prognostic groups (CCI ≥ 1), using the optimal cut-off categories of the CCI, which were selected with the intent of generating preliminary data with a better intra-group difference in survival time.
To study the temporal response to low SMN activity in the whole organism, we compared the GO terms in the 2nd and 3rd instar samples (using 20% cut off per category).
In addition, if muscle area was introduced as a continuous variable and not as a sex-related cut-off category, sex disappeared as independent predictor of mortality.
The above-mentioned mean value of serum VEGF (1069.4 pg ml−1) was chosen as the cut-off category, yielding the sensitivity of 100% and the specificity of 88.9% for detecting early disease relapse.
The SDQ can also be split into 'normal', borderline' and 'abnormal' categories using certain cut off points, where children in the abnormal category are classed as 'cases' of psychological distress.
Sensitivity and therefore utility of TLC to identify immuno-suppressed children may be improved by raising the TLC cut off levels across the various age categories.
These RRs are also comparable with our results, but it should be noted that the cut offs between categories and the reference categories are not the same between studies (we use quartiles based on equal percentage ranges with a reference category of < ≈18%).
