An International Effort to Improve Methods of Data Collection and Exposure Assessment for Community-based Case-Control Studies of Occupational Disease.
The authors recommend that an international effort be made to develop standardized questionnaires for collecting occupational exposure information and to develop standard assessment procedures for evaluating occupational exposures in community-based case-control studies. Such standardization should improve the quality and credibility of findings from this type of study, as well as the comparability of results across studies.
