Table 4

 Multivariate models for the prediction of various parachuting related* injury outcomes among US Army Airborne School trainees, 1985–2002

Model outcome Ankle injury Severe ankle injury† Musculoskeletal injury‡ Any traumatic injury‡ Multiple injury
OR§ 95% CI OR 95% CI OR 95% CI OR 95% CI OR 95% CI
*Parachuting cause of injury code.
†Ankle injury hospitalization with ankle procedure.
‡Excludes ankle injuries.
§Odds ratio, adjusted for all model covariates.
¶Jump week training dates were as follows: pre-brace (01/01/85–30/09/93), brace protocol (01/01/94–30/09/00), post-brace (01/10/00–31/12/02).
