Diagnostic yield of the different microbiological techniques
| Diagnostic test P/N (%) | Total group number (%) | BVO number (%) | TVO number (%) | PVO number (%) | Significance |
|---|---|---|---|---|---|
| Blood culture | 57/152 (37.5) | 29/70 (41.4) | 0/27 (0)* | 23/55 (41.8) | p < 0.0000 |
| Bone biopsy culture | 56/114 (49.1) | 9/37 (24.3) | 16/34 (47) | 31/43 (72.1%)* | p < 0.00005 |
| Culture of other specimens | 44/63 (69.8) | 4/10 (40) | 8/16 (50) | 32/37 (86.5%)* | p < 0.0001 |
P/N = number of positive results/total number of performed studies. P = positive test, N = negative test. * Significant difference with respect to the other groups. Other abbreviations as in table 2.
