Demographic Characteristics of Study Participants and Biosample Collection Timelines. Participants' age, duration of service, as well as pre-OP and post-OP exposure time-point for DANA, blood collection, and symptom surveys are indicated. Levels of OP exposure derived from left shoulder B3 sensors from all participants are displayed as the peak pressure (psi) and cumulative impulse (psi × time) levels are displayed for each day (mean + SD each day, based on all participants).
