Incidence rate ratio of urinary tract infection in people with and without long-term urinary catheterisation after propensity score matching
| Total follow-up length (person-years) | People having episodes of UTI (n) | Incidence rate of UTI (per 100 person-years) (95% CI) | Rate ratio for UTI (95% CI) P value | |
| People without LTUC (n=429) | 328 | 46 | 14.4 (10.5 to 22.3) | Reference |
| People with LTUC (n=143) | 65 | 22 | 33.8 (22.3 to 51.3) | 2.41 (1.45 to 4.00) P=0.001 |
LTUC, long-term urinary catheterisation; UTI, urinary tract infection.
