Dipstick predictors of laboratory diagnosis of urinary tract infection according to European guidelines.a
| UTI (n = 254) n (%) | No UTI (n = 154) n (%) | Crude odds ratio (95% CI) | Adjusted odds ratiob (95% CI) | P-value | |
|---|---|---|---|---|---|
| Nitrite | 72 (28) | 7 (9) | 8.31 (3.71 to 18.6) | 6.36 (2.77 to 14.6) | <0.001 |
| Leucocyte (+ or greater) | 217 (85) | 72 (47) | 6.68 (4.17 to 10.7) | 4.52 (2.72 to 7.50) | <0.001 |
| Blood (haemolysed trace or greater) | 186 (73) | 71 (46) | 3.20 (2.10 to 4.87) | 2.23 (1.38 to 3.61) | <0.001 |
| Protein (+ or greater) | 119 (47) | 47 (31) | 2.00 (1.32 to 3.06) | 1.12 (0.69 to 1.83) | 0.643 |

103 colony-forming units per ml.
b
Adjusted mutually for other variables in the model (nitrite, leucocyte and blood). UTI = urinary tract infection.
