2(d) The first paragraph of text on page 1695 of the research paper indicates that 70% (n = 213) in the
resolved group were correctly predicted and
therefore n = 91 in the resolved group were not
Similarly 65% (n = 166) in the treated and
persisted group were correctly predicted and
therefore n = 90 in the treated and persisted group
were not. Use these values and give a contextual
explanation of sensitivity, specificity, positive
predictive value and negative predictive value.​
