From the parmacoepi point of view, the best risk estimator is the relative risk (RR, event rate in exposed/event rate in non-exposed). This cannot be measured in case-controls studies, because the cases and the controls are independent, and the overall event rates are fixed by the cas/control ratio.
Bay of Campeche. Bay of Campeche, also called Gulf of Campeche, Spanish BahÃ­a de Campeche, bay of the Gulf of Mexico, southern Mexico. It is bounded by the YucatÃ¡n Peninsula to the east, by the Isthmus of Tehuantepec to the south, and by southern Veracruz to the west.
The United States and Mexico form the Gulfâs mainland shore, which extends more than 4,000 miles from the Florida Keys to Cabo Catoche, at the northwestern tip of the YucatÃ¡n Peninsula in Mexico. Like the Mediterranean Sea, the Gulf is a semi-enclosed, partially land-locked, intercontinental, marginal sea.
