| Test methods | Positive | Negative | Total | Positive rate (%) | X 2 value | P-value |
|---|---|---|---|---|---|---|
| mNGS | 80 | 12 | 92 | 86.96 | ||
| culture | 18 | 74 | 92 | 19.57 | 83.92 | 0.000* |
| PCT | 18 | 36 | 54 | 30.33 | 44.34 | 0.000* |
| WBC | 16 | 76 | 92 | 17.39 | 89.21 | 0.000* |
| IGRAs | 27 | 43 | 70 | 38.57 | 41.50 | 0.000* |
* indicates that Pearson's chi-square test was used to compare the sensitivity between mNGS and other traditional detection methods. Positive PCT and WBC indicate increased PCT levels and WBC count; negative PCT and WBC indicate normal PCT levels and WBC count.
