Examples of strains with different grades of sensitivity and resistance are shown in Figure 1.
The results show that there is little difference in the sensitivity grade of ecological corridors in Shenzhen.
In the present validation study, the use of various methods simultaneously in the analyses allowed a better view of the importance and the sensitivity grade of each one.
PCR based tests are able to detect very low levels of virus, which are often transient and not of clinical significance, and quantitative assays with thresholds for positivity of approximately 104 HPV copies in a smear give much better specificity and little loss of sensitivity for high grade CIN [ 10].
For the detection of histological grade ≥1B sensitivity, specificity, PPV, and NPV were 63 %, 70%, 244 %, and 93%%, respectively (Table 2).
Recently, cross-sectional studies have shown a significantly higher specificity for p16/Ki-67 p16/Ki-67ned cytology compared with HPV triage, without a substantial loss of sensitivity for high-grade cytology lesions (Denton et al, 2010; Scomparedt al, 2011; withzensen et al, 2012).
The cut-off value of Ve (0.345) also provided the best combination of sensitivity (88.9%) and specificity (93.3%), which helped differentiate grade II from grade IV gliomas.
At higher cut-off levels in the Finnish trial, the relative sensitivity for any grade of cervical intraepithelial neoplasia decreased substantially.
Study participants were not asked to grade DR; the sensitivity of mild and moderate NPDR was assessed in terms of detection of retinopathy in images with mild and moderate NPDR, respectively.
