| Gender | Age group (years) |
||||||
|---|---|---|---|---|---|---|---|
| 0-18 | 19-39 | 40-59 | 60-79 | ≥ 80 | Age-adjusted* | Age- and gender-adjusted* |
|
| Female | 12 (6.7) | 50 (25.1) | 55 (31.1) | 94 (120.1) | 95 (329.1) | 48.0 (42.5-53.4) | |
| Male | 7 (3.7) | 10 (5.1) | 26 (15.5) | 78 (116.4) | 34 (263.6) | 34.1 (28.6-39.6) | |

NOTE. Data are given as counts (incidence rates per 100,000 person-years), unless otherwise indicated.
*
Incidence rates (95% confidence intervals) are adjusted for US white 2000 census. There is a quadratic increase in the incidence rate of E. coli bloodstream infection with increasing age (p<0.001).
