Annualized national estimates, percentages and rates for persons with non-fatal cyclist injuries sustained while on the road, by selected characteristics, in the US, 2001–4
| Characteristics | Sample cases (n) | Annualized national estimate*† | Percentage† | Rate per 100 000 population (95% CI) |
|---|---|---|---|---|
| AMA, left against medical advice; LWBS, left without being seen by an attending physician; MV, motor vehicle. | ||||
| *National estimates of persons with non-fatal cyclist injuries sustained from an encounter with an MV while on the road, who were treated in US hospital emergency departments. | ||||
| †May not sum to total because of rounding. | ||||
| ‡Estimate may be unstable because coefficient of variation >30%. Rates are not presented for these categories, except for the 20–24 year age group and the month of February where the coefficient of variation was close to 30% (ie, 31.1% and 32.5%, respectively). | ||||
| §Non-fatal rates are not presented for racial/ethnicity groups because race/ethnicity was unknown for a substantial percentage of persons with non-fatal exposures. “Black” includes Hispanic and non-Hispanic blacks; “Hispanic” excludes black Hispanics. | ||||
