They did a cohort study
among members and guests of the households in which turtle meat
was cooked. For each exposure the authors calculated attack rates
and the corresponding relative risks (RR) with a 95% CI. They used
the statistical package STATA 12 (TX: StataCorp LP). The authors
interviewed employees from the local protected marine park. This
investigation was part of public health response activities and
complied with ethical standards of the Ministry of Health.
