  1. aCase with more than one route of exposure, both ingestion and occular
  2. Unweighted N = unweighted counts
  3. N = Estimated Frequency, produced by applying statistical weights provided by CPSC to the unweighted counts
  4. % = distribution by specific characteristics
  5. bCPSC considers a national estimate unstable and potentially unreliable when the weighted estimate is less than 1200
  6. 95% CI: 95% Confidence Interval
