Sensitivity is the true positive rate, specificity is the true negative rate.
From the body of the paper, for their chosen test, their False Positive Rate appears to be 21.2% (100% - 68.8%) and their False Negative Rate appears to be 5.1% (100% - 94.9%). For this type of test, its the false negative rate that we'll really worry about.
