Summary latency measures and 95% confidence intervals (CI) in relation to oil spill and response (OSRC) classes. The summary latency measure incorporates latency or tap rate measures from 7 neurobehavioral function tests. To create this summary measure, some component measures were negated so that a negative relationship between class and the summary measure indicates an adverse effect of exposure. Each OSRC class is compared to administrative workers (administrative support n=223; cleanup on land n=405; decontamination work n=558; cleanup on water n=469; operations n=658; response work n=506). Models are adjusted for age, sex, race, education, smoking status, passive smoking, and binge drinking. See Table A.1 for OSRC class details.
