The purpose of the WHO-sponsored International Collaborative Study of Oral Health Outcomes (ICS-II) was to provide policy-markers and researchers with detailed, reliable, and valid data on the oral health situation in their countries or regions, together with comparative data from other dental care delivery systems. ICS-II used a cross-sectional design with no explicit control groups or experimental interventions. A standardized methodology was developed and tested for collecting and analyzing epidemiological, sociocultural, economic, and delivery system data. Respondent information was obtained by household interviews, and clinical examinations were conducted by calibrated oral epidemiologists. Discussed are the sampling design characteristics for the USA research locations, response rates, samples size for interview and oral examination data, weighting procedures, and statistical methods. SUDAAN was used to adjust variance calculations, since complex sampling designs were used.
世界卫生组织发起的口腔健康结果国际协作研究（ICS-II）的目的是为政策制定者和研究人员提供有关其国家或地区口腔健康状况的详细、可靠且有效的数据，以及来自其他牙科护理服务体系的比较数据。ICS-II采用横断面设计，没有明确的对照组或实验性干预措施。开发并测试了一种标准化方法，用于收集和分析流行病学、社会文化、经济及服务体系数据。通过家庭访谈获取受访者信息，由经过校准的口腔流行病学家进行临床检查。文中讨论了美国研究地点的抽样设计特点、应答率、访谈和口腔检查数据的样本量、加权程序以及统计方法。由于采用了复杂抽样设计，因此使用SUDAAN软件来调整方差计算。
