Sensitivity and specificity are:
a. Directly related.
b. Inversely related.
c. They mean the same.
(b) Sensitivity & specificity can be adjusted according to cutoff level. Sensitivity can be increased by choosing a higher cutoff to include more TP, this meanwhile will include more FP thus ↓specificity. However, this is not always the case as highly specific highly sensitive tests as well as poorly specific poorly sensitive exist.
