| T517 |
0-141 |
Sentence |
denotes |
Strikingly, most of the respiratory symptoms such as cough, sore throat and sputum production are below the diagonal in ROC space (Figure 8). |
| T518 |
142-401 |
Sentence |
denotes |
The diagonal line in ROC space is where sensitivity equals 1‐specificity, meaning a test that is on the diagonal line has a positive likelihood ratio of 1 and is therefore not diagnostic because disease probability is left unchanged after conducting the test. |
| T519 |
402-579 |
Sentence |
denotes |
Tests that lie below the diagonal line have a positive likelihood ratio that is smaller than 1, meaning the probability of COVID‐19 disease decreases when this test is positive. |
| T520 |
580-768 |
Sentence |
denotes |
For example, in Sun 2020a, pretest probability of COVID‐19 is 6.9%; probability decreases to 6.4% when the patient has a cough and increases to 8.0% when the patient does not have a cough. |
| T521 |
769-858 |
Sentence |
denotes |
We hypothesise on the reason for this counterintuitive finding in the discussion section. |
| T522 |
859-1035 |
Sentence |
denotes |
In contrast to respiratory features, systemic features are mostly above the diagonal line (Figure 9), suggesting that they do increase the probability of COVID‐19 when present. |
| T523 |
1036-1232 |
Sentence |
denotes |
Gastrointestinal symptoms and cardiovascular features are clustered in the bottom left corner or on the diagonal line suggesting that they have very little diagnostic value (Figure 10; Figure 11). |
