Abstract
The Cooperative Studies Program Coordinating Center provided the data management, administrative, and statistical support to the Global Enteric Multicenter Study (GEMS). The GEMS study, the largest epidemiological study in the diarrheal disease area among children <5 years of age, was carried out in 4 African countries and 3 Asian countries. Given the geographical and geopolitical differences among the countries, the administration of a centralized data management operation was a major challenge. The sheer volume of the data that were collected, regular transfer of the data to a centralized database, and the cleaning of the same also posed some challenges. This paper outlines the details of the support that the data coordinating center provided and the challenges faced during the course of the study.
